edu.ucla.sspace.matrix.RowMagnitudeTransform.transform()
Computes the Term Frequency-Inverse Document Frequency for a given value where {@code value} is the observed frequency of term {@code row} in document {@code column}. @param row The index speicifying the term being observed @param column The index specifying the document being observed @param value The number of occurances of the term in the document. @return the TF-IDF of the observed value
