NAME

6       zpt - paste matrices or permutations
7

SYNOPSIS

9       zpt [OPTIONS] <Out> [<Inp> ...]
10

DESCRIPTION

12       This program reads matrices from one or more input files and pastes the
13       pieces together to one matrix.  The way in which  the  pieces  are  put
14       together  is  controlled by two parameters, NRows and NCols.  For exam‐
15       ple,
16
17         zpt -r 2 -c 3 x aa ab ac ba bb bc
18
19       would paste together 6 matrices in two rows  and  three  columns.   The
20       resulting matrix is written to "x" and looks like this:
21
22         aa ab ac
23         ba bb ba
24
25       The  file  name  "-"  is treated specially: No file is read in, and the
26       corresponding piece of the output matrix is left empty.   This  can  be
27       used to calculate the direct sum of two representations. For example,
28
29         zpt -r 2 -c 2 A+B A - - B
30
31       creates the following matrix in block diagonal form:
32
33         A 0
34         0 B
35
36       If  only  one  of  NRows and NCols is specified, the other parameter is
37       assumed to be one.
38
39   Permutations
40       The program can also paste permutations, i.e., copy  permutations  from
41       several  files  into  one  file.   In this case, -c cannot be used. For
42       example,
43
44         zpt all perm1 perm2 perm3
45
46       writes the permutations from "perm1", "perm2",  and  "perm3"  into  the
47       file  "all".   Each  of the input file may contain one or more permuta‐
48       tions.  Of course all permutations must have the  same  degree.   Note:
49       pasting  permutations  is  supported  only for compatibility with older
50       versions of the MeatAxe.
