Iterative reconstruction using the Griffin-Lim method.

This figure shows a spectrogram of an iterative reconstruction of the target spectrogram using the Griffin-Lim projection method.

The BFGS method makes use of the minFunc software. To use the BFGS method, please install the minFunc software from: http://www.cs.ubc.ca/~schmidtm/Software/minFunc.html.
