Math::GSL::Diff - Numerical differentiation routines
use Math::GSL::Diff qw/:all/;
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);
