These functions calculate fractional or complex order derivatives, when the order changes with time. Riemann-Liouville, Caputo and Grünwald-Letnikoff definitions are provided; the three variations considered by Lorenzo and Hartley are considered. Fuzzy supervised implementations in Simulink, based upon Oustaloup's Crone approximations, are also provided.
