SPLINTER (SPLine INTERpolation) is a library for multivariate function
approximation implemented in C++. The library can be used for function
approximation, regression and data smoothing.

%description -n %{shlib}
SPLINTER (SPLine INTERpolation) is a library for multivariate function
approximation implemented in C++. The library can be used for function
approximation, regression and data smoothing. Currently,
the library contains the following implementations:

1. tensor product B-splines,
2. radial basis functions, including the thin plate spline, and
3. polynomial regression.

The coefficients in these models are computed using ordinary least
squares (OLS). The name of the library, SPLINTER, originates from the
tensor product B-spline implementation, which was the first of the
methods to be implemented.
