If applied to a matrix, the function FILTFILT (Signal Processing Toolbox) calls itself recursively for each column. Internally FILTER is called twice, but this can be performed with a matrix directly to avoid the unnecessary overhead. For a [100 x 100] matrix FILTFILT is about 10 times faster... Platforms: Matlab

Let us assume the signal model:Y(k)=HX(k)+B(k)This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources. See reference [CHE91] Chen.... Platforms: Matlab

Let us assume the following MIMO model:Y(k)=HX(k)+Y(k)This file can detect the number of sources, i.e the size of the vector X(k) from the received signal Y(k). The noise is assumed spatially white and the number of receivers must be strictly greater than the number of sources. See Reference... Platforms: Matlab
