The positive definite symmetric square matrices have unique square roots. This paper describes two iterative methods using the concepts of interval analysis for enclosing the square root S of a positive definite symmetric square matrix A. By this, we mean A = S 2. The second method is tested ...
Hello i would like to find the square root of a symmetric and positive definite matrix. If i use chol (Cholesky factorization), the upper triangular matrix can be used as the original matrix square root or i need to do some more passages?
we take the first step in getting the best of both worlds — establishing global convergence and obtaining a good rate of convergence for the problem of computing squareroot of a positive definite (PD) matrix, which is a widely studied problem in numerical linear algebra with applicat...

However, for info decomposed using lower matrix L, as L*L^T, Shouldn't it be "L^T" that should be multiplied to the left of the residual? Also, to compute the sqrt of the information matrix, can I use SVD decomposition? My information matrix is sometimes Positive Semi-definite, not ...
The LDL Solver block solves the linear system of equations SX = B by applying LDL factorization to the Hermitian positive definite square matrix at the S port.
