NAME

       Math::GSL::BSpline - Functions for the computation of smoothing basis splines

SYNOPSIS

           use Math::GSL::BSpline qw/:all/;

DESCRIPTION

       gsl_bspline_alloc($k, $nbreak)
           This function allocates a workspace for computing B-splines of order $k. The number of
           breakpoints is given by $nbreak. This leads to n = $nbreak + $k - 2 basis functions.
           Cubic B-splines are specified by $k = 4.

       gsl_bspline_free($w)
           This function frees the memory associated with the workspace $w.

       gsl_bspline_ncoeffs($w)
           This function returns the number of B-spline coefficients given by n = nbreak + k - 2.

       gsl_bspline_order
       gsl_bspline_nbreak
       gsl_bspline_breakpoint
       gsl_bspline_knots($breakpts, $w)
           This function computes the knots associated with the given breakpoints inside the
           vector $breakpts and stores them internally in $w->{knots}.

       gsl_bspline_knots_uniform($a, $b, $w)
           This function assumes uniformly spaced breakpoints on [$a,$b] and constructs the
           corresponding knot vector using the previously specified nbreak parameter.  The knots
           are stored in $w->{knots}.

       gsl_bspline_eval($x, $B, $w)
           This function evaluates all B-spline basis functions at the position $x and stores
           them in the vector $B, so that the ith element of $B is B_i($x). $B must be of length
           n = $nbreak + $k - 2. This value may also be obtained by calling gsl_bspline_ncoeffs.
           It is far more efficient to compute all of the basis functions at once than to compute
           them individually, due to the nature of the defining recurrence relation.

           For more information on the functions, we refer you to the GSL offcial documentation:
