UFMSTACK control QUIET
Outputs a “stacked” matrix using a set of filenames read from a text file “control”.
More specifically the first record in control gives the name of the output matrix to be stacked while each following record lists a sub-matrix to be stacked. The number of matrices to be stacked is therefore dictated only by the number of records in the file. Thus it is not otherwise restricted by the number of matrices (8) that MX can store internally (unlike MXSTACK, 10.20.9) since each matrix to be stacked is read, copied and then closed immediately.
The matrices to be stacked may be either “square” or “stacked” with the restriction that they must all be the same size, e.g., all square, all with 3 sub-levels, etc.
If the second parameter is ‘QUIET’ then the program runs in quiet mode; see 14.9.
