  1. Each row represents a pattern, and each column represents a class such that entry P(i, j) is the ith pattern of class j. An entry of 1 means upregulated while an entry of -1 means downregulated. For example, the first row indicates that a patterned gene is upregulated in class 1 compared to all the other three classes.
