| density | Density of the non-zero elements |
| Parameter | Description |
|---|---|
| S | a sparse matrix. |
R = sprand(S) creates a sparse matrix that has the same sparsity pattern as the matrix S, but with uniformly distributed random entries.
R = sprand(m,n,density) creates a random m-by-n sparse matrix with approximately density*m*n uniformly distributed nonzero entries for density in the interval [0,1].
