Whats the code for this? MATLAB

0O (2k +1)nt F(t) =-22k + 1 * sin--. T Create a program which will calculate the first 40 terms of the infinite series. Plot the composite square wave (F(t)) Create a separate plot which overlays plots from just the first four (4) terms of the fourier series (all sine waves) You may choose the period of this square wave but plot it such that t spans two periods (e.g.t -T: small step: T)
