**Syntax**

**Description**

```
r = sprank(A)
```

is the structural rank of the sparse matrix `A`

. Also known as maximum traversal, maximum assignment, and size of a maximum matching in the bipartite graph of `A`

.

Always `sprank(A) >= rank(full(A))`

, and in exact arithmetic `sprank(A) == rank(full(sprandn(A)))`

with probability one.
