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 -- otherwise 'natural' values are used.

The Perl module is available as 32-bit and 64-bit:

  • For the 32-bit module you need to use perl.
  • For the 64-bit module you need to use perl_64bit.
