PermutMatrix is a program to perform graphical analysis of a dataset.It implements several types of cluster analysis and a variety of methods for statistical seriation.
Numerical values from the dataset are converted into a gradation of colours.
Then rows and/or columns are permuted in such a way that a structure appears. A row or column ordering that reveals a statistical organisation in the dataset is searched.
