setContrastEnhancedVector

protected static boolean setContrastEnhancedVector(float[] aDataVector,
 float[] aBufferVector,
 Utils.MinMaxValue[] aMinMaxComponents,
 float aThresholdForContrastEnhancement)

Transforms original data vector into corresponding contrast enhanced unit vector (see code). Note: No checks are performed.

Parameters:

aDataVector - Data vector (IS NOT CHANGED)

aBufferVector - Buffer vector for contrast enhanced unit vector derived from data vector (MUST ALREADY BE INSTANTIATED and is set within the method)

aMinMaxComponents - Min-max components of original data matrix

aThresholdForContrastEnhancement - Threshold for contrast enhancement

Returns:

True: Scaled data vector has a length of zero, false: Otherwise
