Constructor

Parameters:

aPreprocessedMatrix - Preprocessed matrix (NOT allowed to be null)

aDataVectorZeroLengthFlags - Flags array that indicates if scaled data row vectors have a length of zero (i.e. where all components are equal to zero). True: Scaled data row vector has a length of zero (corresponding preprocessed vector is set to null in this case), false: Otherwise.

aMinMaxComponentsOfDataMatrix - Min-max components of original data matrix

anOffsetForContrastEnhancement - Offset for contrast enhancement (must be greater zero)

Throws:

IllegalArgumentException - Thrown if an argument is illegal
