I have a column of amplitudes d_n and frequencies Omega both from 1 to 664.
1) How to i create the series? I have attempted V_x=sum(d_n.*cos(Omega.*x)) (which generated all the sin terms with values of d_n and Omega, however I cannot repeat this now for some reason) but then when I attempted to plot, I got error message stating
"cannot convert from syms to double"
2) Then plot the series in sysmbolic mode?
Any information will be appreciated. Regards
