%description
|
|
Math::Symbolic is intended to offer symbolic calculation capabilities to
|
|
the Perl programmer without using external (and commercial) libraries
|
|
and/or applications.
|
|
|
|
Unless, however, some interested and knowledgable developers turn up to
|
|
participate in the development, the library will be severely limited by my
|
|
experience in the area. Symbolic calculations are an active field of
|
|
research in CS.
|
|
|
|
There are several ways to construct Math::Symbolic trees. There are no
|
|
actual Math::Symbolic objects, but rather trees of objects of subclasses of
|
|
Math::Symbolic. The most general but unfortunately also the least intuitive
|
|
way of constructing trees is to use the constructors of the
|
|
Math::Symbolic::Operator, Math::Symbolic::Variable, and
|
|
Math::Symbolic::Constant classes to create (nested) objects of the
|
|
corresponding types.
|
|
|
|
Furthermore, you may use the overloaded interface to apply the standard
|
|
Perl operators (and functions, see the OVERLOADED OPERATORS manpage) to
|
|
existing Math::Symbolic trees and standard Perl expressions.
|
|
|
|
Possibly the most convenient way of constructing Math::Symbolic trees is
|
|
using the builtin parser to generate trees from expressions such as '2 *
|
|
x^5'. You may use the Math::Symbolic->parse_from_string() class method for
|
|
this.
|
|
|
|
Of course, you may combine the overloaded interface with the parser to
|
|
generate trees with Perl code such as "$term * 5 * 'sin(omega*t+phi)'"
|
|
which will create a tree of the existing tree $term times 5 times the sine
|
|
of the vars omega times t plus phi.
|
|
|
|
There are several modules in the distribution that contain subroutines
|
|
related to calculus. These are not loaded by Math::Symbolic by default.
|
|
Furthermore, there are several extensions to Math::Symbolic available from
|
|
CPAN as separate distributions. Please refer to the SEE ALSO manpage for an
|
|
incomplete list of these.
|
|
|
|
For example, Math::Symbolic::MiscCalculus come with Math::Symbolic and
|
|
contains routines to compute Taylor Polynomials and the associated errors.
|
|
|
|
Routines related to vector calculus such as grad, div, rot, and Jacobi- and
|
|
Hesse matrices are available through the Math::Symbolic::VectorCalculus
|
|
module. This module is also able to compute Taylor Polynomials of functions
|
|
of two variables, directional derivatives, total differentials, and
|
|
Wronskian Determinants.
|
|
|
|
Some basic support for linear algebra can be found in
|
|
Math::Symbolic::MiscAlgebra. This includes a routine to compute the
|
|
determinant of a matrix of Math::Symbolic trees.
