.SH NAME
sprand - sparse random matrix
.SH CALING SEQUENCE
.nf
sp=sprand(nrows,ncols,fill [,typ])
.fi
.SH PARAMETERS
.TP 10
nrows
: integer (number of rows)
.TP
ncols
: integer (number os columns)
.TP
fill
: filling coefficient (density)
.TP
typ
: character string (\fV'uniform'\fR (default) or \fV'normal'\fR)
.TP
sp
: sparse matrix
.SH DESCRIPTION
\fVsp=sprand(nrows,ncols,fill)\fR returns a sparse matrix \fVsp\fR
with \fVnrows\fR rows, \fVncols\fR columns and approximately
\fVfill*nrows*ncols\fR non-zero entries.
.LP
If \fVtyp='uniform'\fR uniformly distributed values are generated.
If \fVtyp='normal'\fR normally distributed values are generated.
.SH EXAMPLE
.nf
W=sprand(100,1000,0.001);
