StandardizeColumns 

The method StandardizeColumns standardizes the data columns of the matrix. This means that the elements of the data matrix are shifted and scaled in a way that each column of the matrix has a zero mean and unit standard deviation. The means, and the standard deviations of all columns are returned in the parameters means and stddevs. Please note that size of the vector parameters means and stddevs has to be equal to NrOfColumns. The parameters means and stddevs may be set to NIL, if these results are not needed.
