Multivariate De-noising Added

A new command-line function (wmulden) and a new GUI (Multivariate Denoising from the wavemenu initial window) for de-noising a matrix of signals have been added. Both the function and GUI take into account the signals themselves and the correlations between the signals. A two-step process is used. First, a change of basis is performed to deal with noise spatial correlation de-noising in the new basis. Then, a principal component analysis is performed to take advantage of the deterministic relationships between the signals, leading to an additional de-noising effect.

Multiscale Principal Component Analysis Added

A new command-line function (wmspca) and a new GUI (Multiscale Princ. Comp. Analysis from the wavemenu initial window) for simplifying a matrix of signals have been added. Both the function and GUI take into account the signals themselves and the correlations between the signals. The multiscale principal component analysis mixes wavelet decompositions and principal component analysis.
