Polynomial is a C++ class facilitating the evaluation of polynomials of a single indeterminate.

Here’s some C++ functions which evaluate Chebyshev polynomials: Chebyshev Polynomials of the first kind: T0(x):     template <class T> T T0(const T& x); T1(x):     template <class T> T T1(const T& x); T2(x):     template <class T> T T2(const T& x); Tn(x):     template <class T> T Tn(unsigned int n, const T& x); Chebyshev Polynomials of the second kind: … Continue reading “C++ Functions to Evaluate Chebyshev Polynomials”

Here’s some C++ functions which evaluate Legendre polynomials:

P₀(x):
double P0(double x) ;

P₁(x):
double P1(double x) ;

P₂(x):
double P2(double x) ;

P_n(x):
double Pn(unsigned int n, double x) ;

These are inline functions defined in the header file, legendre.h:

While rewriting some data analysis software I developed many years ago (the original was written in K & R C, the new version will be written in C++), I stumbled upon The Matrix Template Library (MTL). MTL is a library that provides comprehensive linear algebra functionality for a wide variety of matrix formats. I was … Continue reading “Matrix Template Library”
