Share Cite lymphom speicheldrüseWebA = A T. Let A be a symmetric, positive-definite matrix. There is a unique decomposition such that. A = L L T. where L is lower-triangular with positive diagonal elements and L T is its transpose. This decomposition is known as the Cholesky decompostion, and L may be interpreted as the ‘square root’ of the matrix A. lymphom stadiumThe Characteristic Set Method is the first factorization-free algorithm, which was proposed for decomposing an algebraic variety into equidimensional components.
