How can I compute an inverse of a large and sparse matrix approximately?

18 October 2017 1 2K Report

Inverse of matrices are needen in both nonlinear and linear preconditioing (see Additive Shcwarz). Since it is too costly, I am searching how to calculte the inverse of a matrix in an approximate way.
