NAME
	Math::Derivative - Numeric 1st and 2nd order differentiation

SYNOPSIS
	   use Math::Derivative qw(Derivative1 Derivative2);
	   @dydx=Derivative1(\@x,\@y);
	   @d2ydx2=Derivative2(\@x,\@y);
	   @d2ydx2=Derivative2(\@x,\@y,$yp0,$ypn);

DESCRIPTION
       This Perl package exports functions for performing numerical first
       (Derivative1) and second Derivative2) order differentiation on vectors
       of data. They both take references to two arrays containing the x and y
       ordinates of the data and return an array of the 1st or 2nd derivative
       at the given x ordinates. Derivative2 may optionally be given values to
       use for the first dervivative at the start and end points of the data -
       otherwiswe 'natural' values are used.
