Fuzzy Control System for a Tanker Ship This program simulates a fuzzy control system for a tanker ship. It has a fuzzy controller with two inputs, the error in the ship heading (e) and the change in that error (c). The output of the fuzzy controlle

function [xphi, phi, xpsi, psi] = Plot_Multiwavelet(H, r, m, n_refine) Compute the point values of the scaling function and wavelet(s) at all points of the form n*dx which fall inside the support of phi.
