Details
Our IPEMPeriodicityPitch function uses Matlab's xcorr function (in fact, it's part of the Signal Processing Toolbox) for auto-correlation calculation.
In Matlab 6.0 the resulting vector coming out of xcorr is 'flipped' compared to how it was in Matlab 5.3.1 ([ 1 2 3 ] now comes out as [ 3 2 1 ] !) Because of this, the results from IPEMPeriodicityPitch are incorrect when using the Matlab 6.0 version of the IPEM Tooolbox...
This new version fixes this problem.
