Opening a matrix

To analyze a gg-matrix you need a matrix written in mfile format . The default extension of the matrix filename is .mtx. Furthermore you need the projection on the x- or y-axis with the default extensions .prx or .pry. All three files must be located in a directory with the same basename as the matrix, e.g. see table 2.1 on page :

To open the matrix for analysis use the hotkey M and you will be queried the name of the directory containing the matrix.
