Non-negative matrix factorization

Positive Semi-Definite Matrix 3: Factorization of Invertible Matrices

Matrix Theory: Let A be an invertible nxn matrix with complex entries. Using the square root result from Part 1, we show that A factors uniquely as PX, where P is unitary and X is (Hermitian) positive definite.
