Abstract
In this paper we investigate structured backward errors for three kinds of generalized saddle point systems where the matrix is not symmetric and its (2,2) block is not zero and has perturbations. Computable formula of backward errors are derived. The expressions are useful for testing the stability of practical algorithms.
