Rank-Augmented LU-Algorithm for Computing Generalized Matrix Inverses
Sagar Sen, E. V. Krishnamurthy · IEEE Transactions on Computers · 1974
A rank-augmnented LU-algorithm is suggested for computing a generalized inverse of a matrix. Initially suitable diagonal corrections are introduced in (the symmetrized form of) the given matrix to facilitate decomposition; a backward-correction scheme then yields a desired generalized inverse.
