Sounds like you're trying to do inner matrix multiplication rather than element by element multiplication
possibly here: (a line number where the error occurred might be handy)
*an*cos*(2*pi*f0*n.'*t) + *bn*sin*(2*pi*f0*n.'*t
instead of
an.*cos(2*pi*f0*n.'*t) + bn.*sin(2*pi*f0*n.'*t

Your ‘an’ and ‘bn’ are (1x4) vectors, and ‘t’ is (1x500).
One way to avoid it is to transpose ‘an’ and ‘bn’ to column vectors:
s = s + a0 + an'*cos(2*pi*f0*n.'*t) + bn'*sin(2*pi*f0*n.'*t);
I do not know what you want for a final result. If you want a single row vector for each ‘n’, sum them:
s = s + a0 + sum(an'*cos(2*pi*f0*n.'*t) + bn'*sin(2*pi*f0*n.'*t));
