libmath-derivative-perl - 1.01-1.1 main

Math::Derivative exports functions for performing numerical first
and second order differentiation on data. The functions 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. The 2nd derivative may optionally be given values to use
for the first derivative at the start and end points of the data -
otherwise 'natural' values are used.
