MSPAI

Modified Sparse Approximate Inverses -- UNDER CONSTRUCTION!!!

Based upon the well-known sparse approximate inverse preconditioner SPAI, we developed the modified sparse approximate inverse (MSPAI) preconditioner.

Theory

MSPAI is a preconditioner for large sparse and ill-conditioned systems of linear equations. We extended the basic SPAI minimization

to target form and further generalized it in order to add additional probing constraints:
