fgl_deriv

Fractional derivative. Compute the fractional derivative of a sampled function using Grunwald-Letnikov formulation.This implementation is similar to that of Bayat 2007 (fderiv) but uses vectorization for faster computation with Matlab. Type `help fgl_deriv` for information on usage. Feel free to rate if you find this useful, and leave a comment if you have improvements in mind.
