MeatAxeFileInfo := "matrix field=5 rows=100 cols=100";Other header formats are supported for compatibility with older versions of the MeatAxe.
After an old type 1 header, the format of the data follwing the header is fixed. There must be at most 80 characters per line, lines must be filled as much as possible, and each row of the matrix starts with a new input line. There are no blanks allowed to separate numbers. In all other modes, the data part consists of a sequence of integers in free format, separated by any combination of blanks, tabs, or newlines.
