sprand — sparse random matrix
sp=sprand(nrows,ncols,fill [,typ])
| nrows | : integer (number of rows) |
| ncols | : integer (number of columns) |
| fill | : filling coefficient (density) |
| typ | : character string ('uniform' (default) or 'normal') |
| sp | : sparse matrix |
sp=sprand(nrows,ncols,fill) returns a sparse matrix sp with nrows rows, ncols columns and approximately fill*nrows*ncols non-zero entries.
If typ='uniform' uniformly distributed values on [0,1] are generated. If typ='normal' normally distributed values are generated (mean=0 and standard deviation=1).
W=sprand(100,1000,0.001);
