Matlab waterfall fft

WebI am trying to implement a real time spectrogram and I am not sure that I am implementing it the right way. First I decided to use Matlab, I was taking a short recording of lets say 0.1 seconds and then perform the FFT on that array of numbers which basically consists of the amplitude of lets say a 11025 sampling rate in that 0.1 seconds.
