differint 0.1

Collection of algorithms for numerically calculating fractional derivatives.

This package is used for numerically calculating fractional derivatives and integrals (differintegrals). Various methods are used, which correspond to varying definitions of the differintegral.

To use the Grunwald_Letnikov differintegral of order 0.5 with a user-defined function ‘func’, do:

import differint
fracderiv_f = differint.GL(0.5, func)

You can also specify the endpoints of your domain (default is [0,1]) and the number of points to use (default is 100).

import differint
fracderiv_f = differint.GL(0.5, func, 0., 1., 100)
