Cholesky decomposition Conceptually the simplest computational method of spectral factorization might be Cholesky decomposition.'' For example, the matrix of could have been found by Cholesky factorization of . The Cholesky algorithm takes a positive-definite matrix and factors it into a triangular matrix times its transpose, say . This is equivalent to post-multiplication of A by an n ´ n upper-triangular matrix E which is non-singular: AE = F, where non-zero columns of F are orthonormal. Thus A = FE -1 = FG, where G = E -1 being inverse of an upper-triangular matrix is upper-triangular. Note that r(a) = r(F) and so precisely r(A) columns of F are non-zero.
