Was using MA28 and was concerned about the amount of fill-in. Example in test set is of order 991 but is indicative of structure of larger matrices (to order 3000) from the same modeling exercise.

Fill-in using MA28 with u=0.1 is six times original number of nonzeros.

Matrices in this set:

JPWH 991 (real unsymmetric, 991 by 991, 6027 entries), Computer random simulation of a circuit physics model
