Declaration:procedure StandardizeRows (means, stddevs: TVector);

The method StandardizeRows standardizes the data rows of the matrix. This means that the elements of the data matrix are shifted and scaled in a way that each row of the matrix has thereafter a zero mean and unit standard deviation. The means and the standard deviations of all rows are returned in the parameters means and stddevs.

Please note that size of the vector parameters means and stddevs has to be equal to NrOfRows. The parameters means and stddevs may be set to NIL, if these results are not needed.

Hint: Background information on the standardization of data can be found in Fundamentals of Statistics.
