نام (NAME)
       gomtst - compute statistics on sparse matrix orderings

خلاصه دستور (SYNOPSIS)
       gotst [options] [gfile] [ofile] [lfile]


توضیحات (DESCRIPTION)
       The gotst program computes, in a sequential way, statistics on a sparse
       matrix ordering, such as fill-in, operation count, and separator tree
       parameters: minimum, maximum, average height and variance of its
       leaves.

       Source graph file gfile can only be a centralized graph file. File
       ofile represents the ordering of the symmetric sparse matrix the
       pattern of which is represented by gfile. The resulting statistics are
       stored in file lfile. When file names are not specified, data is read
       from standard input and written to standard output. Standard streams
       can also be explicitly represented by a dash '-'.

       When the proper libraries have been included at compile time, gtst can
       directly handle compressed graphs, both as input and output. A stream
       is treated as compressed whenever its name is postfixed with a
       compressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The
       compression formats which can be supported are the bzip2 format
       ('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma').

       Since gotst performs sequentially the symbolic factorization of matrix
       gfile in order to compute fill-in and operation count numbers, this
       program can take a long time or even run out of memory, when applied to
       very large graphs.

گزینه‌ها (OPTIONS)
       -h     Display some help.

       -v     Do not account for vertex weights when computing factorization
              costs.

       -V     Display program version and copyright.

مثال (EXAMPLE)
       Display statistics on ordering brol.ord of graph brol.grf:

           $ gotst brol.grf brol.ord
