Class Summary
CholeskyDecomposition CholeskyDecomposition It is a special case of LU decomposition applicable only if matrix to be decomposed is symmetric positive definite.
EigenvalueDecomposition EigenvalueDecomposition If A is symmetric, then A = V*D*V' where the eigenvalue matrix D is diagonal and the eigenvector matrix V is orthogonal.
LUDecomposition LUDecomposition For an m-by-n matrix A with m >= n, the LU decomposition is an m-by-n unit lower triangular matrix L, an n-by-n upper triangular matrix U, and a permutation vector piv of length m so that A(piv,:) = L*U.

QRDecomposition QRDecomposition For an m-by-n matrix A with m >= n, the QR decomposition is an m-by-n orthogonal matrix Q and an n-by-n upper triangular matrix R so that A = Q*R.
SingularValueDecomposition SingularValueDecomposition For an m-by-n matrix A with m >= n, the singular value decomposition is an m-by-n orthogonal matrix U, an n-by-n diagonal matrix S, and an n-by-n orthogonal matrix V so that A = U*S*V'.
