How to draw it in matlab?

Fourier series approximations over square signal function, x(t), for k=1, k=5, k=20 and k=59. Use the equations in Fourier series and programming it using matlab script to plot these graphs.

what have you tried so far? Ask some specific questions and post the codes you have tried along with error messages or unexpected results that you're getting.

1) Use Matlab software to draw a graph of the Fourier series approximations over square signal function, x(t) (like the pic i attach), for k=1, k=5, k=20 and k=59. Use the equations in Fourier series and programming it using matlab script to plot these graphs. (Provide code and plot the graph in mWord)

nothing since i just start learning using matlab.i want to create the signal function like the pic that i attach. since i does not have much basic in it that is why i have been asking.
