sprand - sparse random matrix

### Calling Sequence

  `sp=sprand(nrows,ncols,fill [,typ])`

### Parameters

- `nrows` : integer (number of rows)
- `ncols` : integer (number of columns)
- `fill` : filling coefficient (density)
- `typ` : character string (`'uniform'` (default) or `'normal'` )
- `sp` : sparse matrix

### Description

`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).

### Examples

    W=sprand(100,1000,0.001);
