mm2gv


SYNOPSIS
       mm2gv [ -cluv?  ] [ -ooutfile ] [ file ]

DESCRIPTION
       mm2gv  converts  a sparse matrix of the Matrix Market format to a graph
       in the GV (formerly DOT) format.

OPTIONS
       The following options are supported:

       -c     This flag causes mm2gv to assign colors to the edges. The matrix
              element  is scaled to the range [0,1] depending on where it lies
              between the minimum and maximum set matrix values.  This  scaled
              value  is  used as the "wt" attribute of the corresponding edge.
              In addition, this scalar value is mapped to an RGB value,  which
              is stored as the edge "color".

       -l     If  set, mm2gv attaches a label to the graph indicating the base
              name of the input file, and the number of nodes and edges.

       -u     If specified, the graph is assumed to be undirected. By default,
              the graph generated is directed.

       -v     This  flag  causes mm2gv to store the matrix values as the "len"
              attribute of the corresponding edge.

       -ooutfile
              Prints output to the file outfile. If not given, mm2gv uses std-
              out.


       OPERANDS
              The following operand is supported:

       file    Name of the file in MatrixMarket format.  If no file operand is
               specified, the standard input will be used.

RETURN CODES
       Return 0 if there were no problems during conversion; and  non-zero  if
       any error occurred.
