Generalized Complex Pursuit code

In the context of blind source separation for modal analysis, this algorithm permits to estimate the separation matrix and source signals from the measured vibration response of a structure by jointly diagonalizing the cross-correlation matrices of filtered versions of signals using Pham's algorithm.
