WebThe modified Bruhat decomposition (2.2) exists for any nonsingular matrix A E C”’ n, and the permutation matrix P is determined uniquely. Proof. We show that A can be reduced to a permutation matrix by sequence of pre- and postmultiplications using appropriate lower and upper triangular matrices.
