RANDOM: a random sparse matrix

from the MMDELI

Matrix Generator RANDOM
Source: B. Miller (NIST)
Discipline: numerical linear algebra
Language: Java applet
Output format: Matrix Market format

This is a Java applet which generates creates a sparse matrix whose nonzero elements take values uniformly distributed on [MINVAL,MAXVAL]. Approximately DENSITY*M*N elements are nonzero, and their positions are uniformly distributed. A nonzero diagonal can be requested.

This generator was developed by Bruce Miller of NIST.

Parameters:

Nnumber of rows
Mnumber of columns
NZDIAGswitch to force non-zero diagonal
DENSITYratio of number of nonzeros to number of elements
MINVALsmallest value for nonzero elements
MAXVALmaximum value for nonzero elements
