For example in SymPy 1.5 you could do Symbol('x').has('x') and the string 'x' passed to has would be sympified to a symbol so that the result would be True. In SymPy 1.6 this will raise an error because the string 'x' can not be sympified using strict sympification. (#19251 by @oscarbenjamin) + * Remove deprecated bounded, unbounded and infinitesimal. Deprecated since version 0.7.6 (issue #8071) (#18503 by @Smit-create) + * Relational is no longer a subclass of Expr and does not produce nonsensical results in arithmetic operations. This affects all Relational subclasses (Eq, Ne, Gt, Ge, Lt, Le). It is no longer possible to call meaningless Expr methods like as_coeff_Mul on Relational instances. (#18053 by @oscarbenjamin) + * Expr now uses cooperative dispatch for binary operations so it is possible for non-Expr Basic subclasses to override the behaviour of e.g. a + b where one of a or b is an instance of Expr. This also means that any non-Expr Basic subclasses can not depend on Expr.__add__ to create Add(a, b): if a class is not a subclass of Expr and wants to define binary operations with Expr it must do so explicitly in its own __add__ method. For classes depending on this this is not a backward compatible change. (#18116 by @oscarbenjamin) + > matrices + * The Matrix.is_zero property has been renamed to Matrix.is_zero_matrix. + * Matrix.is_zero is now always False.

(#18464 by @sylee957) + > polys + * BREAKING CHANGE: Poly and PurePoly now subclass Basic rather than Expr. This means that they no longer have various Expr methods such as expand that do not make sense for Poly. Use as_expr to convert the Poly to an Expr before using Expr methods. (#18613 by @oscarbenjamin) + * BREAKING CHANGE: Poly instances with different domains now always compare unequal with p1 == p2 and p1.eq(p2). Previously Poly instances that had the same expression and generators would compare equal even if the domains were different. In some cases it might be necessary to specify the domain when comparing e.g. if p == Poly(x, x, domain='QQ'). (#18613 by @oscarbenjamin) + * DEPRECATION: Mixing Poly with non-polynomial Expr in binary operations is now deprecated. For example Poly(x, x) * exp(x) will give a deprecation warning but still return the Expr x*exp(x) as before. If the Expr can be converted to Poly (e.g. Poly(x, x) * x) then a Poly will be returned. To get an Expr always use the as_expr method first to convert the Poly to an Expr. To get a Poly always use as_poly to convert the Expr to a Poly. (#18613 by @oscarbenjamin) + * DEPRECATION: Passing Poly as the integrand to the integrate function or Integral class is now deprecated. Use the integrate method instead e.g. Poly(x, x).integrate(x) (#18613 by @oscarbenjamin) + > printing + * Removed deprecated Ccodeprinter (Use C89Printer or C99Printer instead).

This also means that any non-Set Basic subclasses can not depend on e.g. Set.__add__ to create Union(a, b): if a class is not a subclass of Set and wants to define binary operations with Set it must do so explicitly in its own __add__ method.

(#18168 by @gschintgen) + * Set now uses cooperative dispatch for binary operations so it is possible for non-Set Basic subclasses to override the behaviour of e.g. a + b where one of a or b is an instance of Set. This also means that any non-Set Basic subclasses can not depend on Expr.__add__ to create Union(a, b): if a class is not a subclass of Set and wants to define binary operations with Set it must do so explicitly in its own __add__ method.

(#17922 by @lglattly) + +------------------------------------------------------------------- +Wed Jan 15 09:50:57 UTC 2020 - Benedikt Fein + +- version update to 1.5.1 + + Deprecate `is_EmptySet` in favor of `is_empty` + + Lambda now requires a tuple rather than a list for the + signature argument (non-tuple iterables are deprecated) + + Eq(expr) now raises ValueError. Eq(expr, 0) should be used + instead. + + Refactory of the units module. Scale factors and dimensions + are now both global and relative to single unit systems. + + get_dixon_matrix() now computes only the necessary monomials + for the Dixon matrix. + + The ProductSet of no sets is no longer the empty set. Instead + is the set consisting of the empty tuple. + + Deprecated tensorhead() and tensorsymmetry() static methods. + + Rational, irrational, transcendental and algebraic now imply + finite in the assumptions system. This means that all symbols + declared as rational, integer, odd etc are now automatically + assumed finite. + + In the (old) assumptions, `complex=True` now implies + `finite=True`. Note that the default assumption for Symbol is + `complex=None`, which allows for the possibility for it to be + infinite. + + The assumptions system is changed so that only finite numbers + can be considered real, positive, negative, nonnegative, + nonpositive or nonzero (since nonzero implies real). This + means that any symbol declared with e.g. real=True is now + automatically considered finite. It also means that infinities + can not be considered positive or negative since they are not + real (e.g. oo.is_positive is now False). + + New assumptions extended_real, extended_positive etc are added + that allow for positive and negative infinity. The equivalent + of `Symbol('x', real=True)` in version 1.4 is now + `Symbol('x', extended_real=True)`. The equivalent of + `Symbol('x', negative=False)` is now + `Symbol('x', extended_negative=False)` although it is usually + better to use `Symbol('x', nonnegative=True)` (which implies + both real=True and finite=True as well). Code that previously + checked `if x.is_positive` should now be written as + `if x.is_extended_positive` if it is intended that infinities + should be allowed. + + Numbers still compare the same as they do in Python + (`Float(1) == 1`) except when they appear in an Expression, + e.g. `x**2.0 != x**2`. + +------------------------------------------------------------------- +Wed Apr 17 12:28:18 UTC 2019 - pgajdos@suse.com + +- version update to 1.4 + + Logic expressions with relations can now be simplifed in a + better way which has impact on e.g. simplification of + piecewise expressions + + The MathML Presentation printer has seen a major improvement + with support configuration and about a hundred new functions. + + Union and Intersection have been improved to, among other + improvements, support Python sets. + + The test procedure has been changed to include code coverage + and code quality checks leading to a number of issues being + identified and removed. + + Unicode support, especially for Python 2.7, has been improved. + + subs and Subs have been improved in a number of ways. + + SymPy objects now renders as LaTeX automatically in Jupyter + notebooks. init_printing is still required to LaTeX render + non-SymPy objects such as lists of expressions or Python ints + +------------------------------------------------------------------- +Mon Oct 29 16:07:24 UTC 2018 - Todd R + +- Fix building on Leap + +------------------------------------------------------------------- +Thu Sep 27 08:48:09 UTC 2018 - Matěj Cepl + +- Update python-sympy-rpmlintrc to reflect current reality. + +------------------------------------------------------------------- +Sun Sep 16 16:00:54 UTC 2018 - Arun Persaud + +- specfile: + * package isympy file and __pycache__ + +- update to version 1.3: + * see https://github.com/sympy/sympy/wiki/Release-Notes-for-1.3 + +------------------------------------------------------------------- +Wed Sep 5 03:52:12 UTC 2018 - arun@gmx.de + +- specfile: + * update copyright year + * removed devel from noarch + +- update to version 1.2: + * Highlights + + Python 3.3 is no longer supported.

The new version is much faster, and includes + fast methods for enumerating only those partitions with a + restricted range of sizes, and counting multiset partitions. (See + the new file sympy.utilities.enumerative.py.) + * distance methods were added to Line and Ray to compute the shortest distance to them from a point. + * The normal_lines method was added to Ellipse to compute the lines from a point that strike the Ellipse at a normal angle. + * inv_quick and det_quick were added as functions in solvers.py to + facilitate fast solution of small symbolic matrices; their use in + solve has reduced greatly the time needed to solve such systems. + * solve_univariate_inequality has been added to sympy.solvers.inequalities.py. + * as_set attribute for Relationals and Booleans has been added. + * Several classes and functions strictly associated with vector + calculus were moved from sympy.physics.mechanics to a new package + sympy.physics.vector. (PRs #2732 #2862 #2894) + * New implementation of the Airy functions Ai and Bi and their + derivatives Ai' and Bi' (called airyai, airybi, airyaiprime and + airybiprime, respectively). Most of the usual features of SymPy + special function are present. Notable exceptions are Gruntz limit + computation helpers and meijerg special functions integration + code. + * Euler-Lagrange equations (function euler_equations) in a new package sympy.calculus (PR #2431). + + Minor changes: + * Some improvements to the gamma function. + * generate_bell now generates correct permutations for any number of elements. + * It is no longer necessary to provide nargs to objects subclassed + from Function unless an eval class method is not defined. (If eval + is defined, the number of arguments will be inferred from its + signature.) + * geometric Point creation will be faster since simplification is done only on Floats + * Some improvements to the intersection method of the Ellipse. + * solutions from solve of equations involving multiple log terms are more robust + * idiff can now return higher order derivatives + * Added to_matrix() method to sympy.physics.vector.Vector and + sympy.physics.dyadic.Dyadic. (PR #2686). + * Printing improvements for sympy.physics.vector objects and + mechanics printing. (PRs #2687, #2728, #2772, #2862, #2894) + * Functions with LaTeX symbols now print correct LaTeX. (PR #2772) + * init_printing has several new options, including a flag + print_builtin to prevent SymPy printing of basic Python types (PR + #2683), and flags to let you supply custom printers (PR #2894). + * improvements in evaluation of imageset for Intervals (PR #2723). + * Set properties to determine boundary and interior (PR #2744). + * input to a function created by lambdify no longer needs to be flattened. + + Backwards compatibility breaks and deprecations: + * the submatrix method of matrices was removed; access the + functionality by providing slices or list of rows/columns to + matrix directly, e.g. A[:, [1, 2]]. + * Matrix([]) and Matrix([[]]) now both return a 0x0 matrix + * terms_gcd no longer removes a -1.0 from expressions + * extract_multiplicatively will not remove a negative Number from a + positive one, so (4*x*y).extract_multiplicatively(-2*x) will + return None. + * the shape of the result from M.cross(B) now has the same shape as matrix M. + * The factorial of negative numbers is now zoo instead of 0. This is + consistent with the definition factorial(n) = gamma(n + 1). + * 1/0 returns zoo, not oo (PR #2813). + * zoo.is_number is True (PR #2823). + * oo < I raises TypeError, just as for finite numbers (PR #2734). + * 1**oo == nan instead of 1, better documentation for Pow class (PR #2606). + +------------------------------------------------------------------- +Sat Jan 11 01:34:28 UTC 2014 - arun@gmx.de + +- update to 0.7.4.1 + * This was a small bugfix release to fix an import issue on Windows (https://github.com/sympy/sympy/issues/2681). + +- update to 0.7.4 (see https://github.com/sympy/sympy/wiki/Release-Notes-for-0.7.4) + +------------------------------------------------------------------- +Thu Sep 26 06:56:12 UTC 2013 - speilicke@suse.com + +- Update to version 0.7.3: + + See https://github.com/sympy/sympy/wiki/Release-Notes-for-0.7.3 +- Use update-alternatives for binaries / man-pages + +------------------------------------------------------------------- +Tue Jan 15 17:39:02 UTC 2013 - p.drouand@gmail.com + +- Initial python3 support + +------------------------------------------------------------------- +Tue Jan 15 17:30:55 UTC 2013 - p.drouand@gmail.com + +- Update to 0.7.2 version: + * pep8 correction: don't include space around * and ** + * radsimp watches for pure radical in denominator + * pep8 E702: one statement per line + * add class name to hash value + * give more explicit error messages + * fix quality and ode constant numbering bug + * mprovements to euler equation solver + * Sparse hash now includes shape + * add hash to SparseMatrix + * raise notimplemented on MatrixExpr.conjugate + * removed cruft print statement +- Fix the shebang RPMLint without make python libraries executables, + it is not the good way + +------------------------------------------------------------------- +Thu Jan 3 17:07:45 UTC 2013 - toddrme2178@gmail.com + +- Fix building on SLES 11 + +------------------------------------------------------------------- +Thu May 3 14:58:12 UTC 2012 - cfarrell@suse.com + +- license update: BSD-3-Clause + Always state the exact version of the license and use SPDX syntax + (http://www.spdx.org/licenses) + +------------------------------------------------------------------- +Sat Feb 25 21:50:14 UTC 2012 - scorot@free.fr + +- fix build for SLE-11 + +------------------------------------------------------------------- +Sun Nov 20 17:59:44 UTC 2011 - werner.ho@gmx.de + +- new version 0.7.1 +------------------------------------------------------------------- +* Mon Mar 29 2010 Werner Hoch - 0.6.7 +- new version 0.6.7 +------------------------------------------------------------------- +* Sun Dec 20 2009 Werner Hoch - 0.6.5 +- fixed site-packages location for openSUSE 11.2 +------------------------------------------------------------------- +* Sun Oct 04 2009 Werner Hoch - 0.6.5 +- new version 0.6.5 +------------------------------------------------------------------- +* Sun Apr 19 2009 Werner Hoch - 0.6.4 +- new version 0.6.4 +------------------------------------------------------------------- +* Mon Nov 24 2008 Werner Hoch - 0.6.3 +- new version 0.6.3 +------------------------------------------------------------------- +* Sat Sep 20 2008 Werner Hoch - 0.6.2 +- fixed wrong man-page in INSTALLED_FILES list + diff --git a/python-sympy.spec b/python-sympy.spec new file mode 100644 index 0000000..c2ee6b7 --- /dev/null +++ b/python-sympy.spec @@ -0,0 +1,113 @@ +# +# spec file for package python-sympy +# +# Copyright (c) 2022 SUSE LLC +# +# All modifications and additions to the file contributed by third parties +# remain the property of their copyright owners, unless otherwise agreed +# upon.
