how do I implement Fourier series.

I now have the a0,an and bn. just wondering that how do I generate the "sum of square wave" and draw it out?

syms n t
w0=pi;
T0=2;
n=1:10;
a0=(1/T0)*int(1,t,0,1)
an=(2/T0)*int(1*cos(n*w0*t),t,0,1)
bn=(2/T0)*int(1*sin(n*w0*t),t,0,1)

There are a whole bunch of postings from people implementing fourier; you should search for them and get back to us with questions that are more specific.
