zpt Options [-r NRows] [-c NCols] Out Inp [Inp ...]
zpt -r 2 -c 3 x aa ab ac ba bb bcwould paste together 6 matrices in two rows and three columns. The resulting matrix is written to "x" and looks like this:
aa ab ac ba bb baThe file name "-" is treated specially: No file is read in, and the corresponding piece of the output matrix is left empty. This can be used to calculate the direct sum of two representations. For example,
zpt -r 2 -c 2 A+B A - - Bcreates the following matrix in block diagonal form:
A 0 0 BIf only one of NRows and NCols is specified, the other parameter is assumed to be one.
zpt all perm1 perm2 perm3writes the permutations from "perm1", "perm2", and "perm3" into the file "all". Each of the input file may contain one or more permutations. Of course all permutations must have the same degree. Note: pasting permutations is supported only for compatibility with older versions of the MeatAxe.
