The flavor 'Matrix' describes a Matrix with r rows and c columns.  Each entry is described by the given random flavor, flav.  The default flavor is integer and the default value for r and c is 10.

The density value is a probability that an entry will be assigned a value.  By default, this value is 1.

Additional arguments can be specified that will be passed to the Matrix constructor.  For example, datatype, shape, etc.

This flavor can be used as an argument to RandomTools[Generate] or as part of a structured flavor.
