Hi , I want to plot my f_E function according to thetas and rs.But pcolor doesnt work.I got ??? Error using ==> pcolor at 55 Color data input must be a matrix.
If anyone helps me , I apreciate it.Thx for your concern.

Your line
pcolor(abs(E(mg,n)))
is after your nested "for" loops, so mg and n will each have their final values from the loop, the scalars M_d+1 and N_cut respectively. So E(mg,n) is a scalar, and abs(E(mg,n)) remains a scalar. You are trying to pcolor() a scalar value, which is not allowed.
You probably want
pcolar(abs(E))
