t=0:0.001:2;
subplot(2,1,1); title('Quadratic Chirp');
y=chirp(t,0,1,150);
spectrogram(y,256,250,256,250,'yaxis');
  1. spectrogram misspelled
  2. wrong use of the subplot, it's before not after doing the drawing
  3. bad parameters on the spectrogram function

that's what you get when using the names of functions on scripts, bad idea, same goes for variables with same name of functions, bad idea!
