Zero padding or not?

Hello all,
I want to estimate the spectrum of a part of a signal by using an 1024 point FFT. The length of the excerpt is 640 samples. Should I zero pad the signal to make its length equal to 1024? Or is it automatically done by Matlab?

fft(x,1024)
Will automatically zero pad your signal to 1024 points and perform FFT
