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.
