       mm2gv - Matrix Market-DOT converters

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

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

       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 gener-
	      ated is directed.

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

	      Prints output to the file outfile. If not given, mm2gv uses stdout.

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