QNormalizeRows


Unit: SDL_matrix
Class: TMatrix
Declaration: procedure QNormalizeRows (RefQuant: double; Medians, QuantDiffs: TVector);

The method QNormalizeRows normalizes each row of the matrix by first substracting the median of the row and then by dividing the subtraction results by the difference of the median and the percentile defined by the parameter RefQuant. This means that all elements of each row are shifted and scaled in a way that the cells of any row exhibit a median of zero and a RefQuant-percentile of one.

The row medians and the differences between the medians and percentiles before the normalisation are returned in the vectors Medians and QuantDiffs.
