How to plot the NMF factorized matrices of a spectrogram as spectrograms too?

I apply non-negative matrix factorization to my spectrogram and obtain the 2 matrices W and H

[W, H] = nmf(mySTFT,rank) % rank =3
% where W and H hold the spectral and temporal information respectively

I would like to visualize W and H to see if i can understand whats going on. Is it possible to make a spectrogram of the Matrix W and H?
