NAME

       Math::GSL::Diff - Numerical differentiation routines

SYNOPSIS

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

DESCRIPTION

       Here is a list of all the functions included in this module :

       "gsl_diff_central"
           This function computes the numerical derivative of the function f at the point x using
           an adaptive central difference algorithm.  The result is an array where the first
           position is an error code (0 for success), the second is derivative value, and the
           third is an estimate of its absolute error.

              my ($success, $result, $error) =
                    gsl_diff_central(sub { return $_[0] ** 1.5 }, 2.0);

       "gsl_diff_backward"
           This function computes the numerical derivative of the function f at the point x using
           an adaptive forward difference algorithm.  Its usage is similar to "gsl_diff_central".

              my ($success, $result, $error) =
                     gsl_diff_backward(sub { return $_[0] ** 1.5 }, 0.0);

       "gsl_diff_forward"
           This function computes the numerical derivative of the function f at the point x using
           an adaptive backward difference algorithm.  Its usage is similar to
           "gsl_diff_central".

              my ($success, $result, $error) =
                     gsl_diff_forward(sub { return $_[0] ** 1.5 }, 1.0);
