A revision of a completion method for inverting matrices and its adaptation to ill-conditioned matrices
William Lee Waltmann · UNI ScholarWorks (University of Northern Iowa) · 1960
An essentially new method for the inversion of n x n matrices, closely related to the method of completion attributed to Sherman, Morrison, and Bartlett, is presented. This revised technique has the added advantages that it can be used for any square matrix, regardless of its conditioning state, and that it can be readily adapted to electronic digital computers.
