Math::GSL::Diff(3)    User Contributed Perl Documentation   Math::GSL::Diff(3)

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);
