To “save” the internal matrix, output it to a binary .ufm matrix file. This is the normal procedure by which a .ufm matrix file is created. Thus the M1 (or MXM1) procedure described in Section 4 uses this output option after reading a .dat file (10.5). The output matrix, referred to as Z in Figure 10.2, may then be further used within the program.
The filename of the new .ufm matrix may either be set interactively at the time of output or pre-defined using the “OUT” keyword on the MX command line (see 10.1.2).
A number of different options, numbered 1 through 15 in the UFM Outputs sub-menu and described below, control the form of the outputs.
