Let T denote an operator on a Hilbert space โข โข , and let f i โ i=1 be a frame for the orthogonal complement of the kernel N T . We construct a sequence of operators n of the form n โข = n i=1 โข g n i f i which converges to the psuedoinverse T โ of T in the strong operator topology as n โ โ. The oper
We investigate different methods for computing a sparse approximate inverse M for a given sparse matrix A by minimizing AM -E in the Frobenius norm. Such methods are very useful for deriving preconditioners in iterative solvers, especially in a parallel environment. We compare different strategies f
