    MATLAB MATLAB plotting error?

    Hello, I've written a piece of code in MATLAB, to depict the function x(t) I have the Fourier coefficients of this function as following: a(k) = 1/(k.*pi)^2 where k is even and otherwise a(k) = 0. also we know that x(t+5) = x(t) my code is : function [zaribX] = Ak(k)...
