A small test for the condestsp function: condestsp gives an estimate of
the condition number K1 in 1-norm of a real sparse matrix A: |

without explicitly computing the inverse of A. condestsp uses a factorization given by
umf_lufact but if you have already computed this one it is recommended to give the pointer to the factorization.

The test consists in forming small sparse matrices (so as to compute K1 exactly with
norm(inv(full(A)),1)) whose values are chosen from the normal distribution. |
