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);
