Compact Schemes for for A+B, A+AB and AA+B
Abstract
Explicit details are presented for calculation of A+ B, AA+ AB and AA+ B where Am×n is any nonzero matrix, A+ is the MoorePenrose pseudoinverse of A and B is any matrix of appropriate dimensions, where the quantities in question are found using only the storage originally allocated to the matrices A and B (together with some simple one dimensional indexing arrays)
