Creation and Calculation of Chebyshev Series
- Function: gsl_cheb_series * gsl_cheb_alloc (const size_t n)
-
This function allocates space for a Chebyshev series of order n
and returns a pointer to a new
gsl_cheb_series
struct.
- Function: void gsl_cheb_free (gsl_cheb_series * cs)
-
This function frees a previously allocated Chebyshev series cs.
- Function: int gsl_cheb_init (gsl_cheb_series * cs, const gsl_function * f, const double a, const double b)
-
This function computes the Chebyshev approximation cs for the
function f over the range (a,b) to the previously specified
order. The computation of the Chebyshev approximation is an
O(n^2) process, and requires n function evaluations.
