I have no idea of this code,,,, please help me.

project1b_fse.m % % Let us compute the Fourier coefficients and the Fourier series % expansions

if true
  % code
endof 4 kinds periodic signals. ///

   T = 2; fo = 1/T;    Ns=1000;%%%
   t = T/2*[-Ns:Ns]/Ns;  N=10;
   n =-N:N;
   x = cos(2*pi*t/T);
   X = cfc(x,t,n)

At last codes, i don't know what 'cfc(x,t,n)' this means.. I'm just guessing it is a fourier coeffiecient relative codes.

As far as I know, cfc is not a built-in MATLAB function. It may be a custom function and you can open function by entering edit cfc in the command window. By going through the code in the function you may get a better idea.
