In linear algebra, the Cholesky decomposition or Cholesky factorization is a decomposition of a Hermitian, positivedefinite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e. g. , Monte Carlo simulations. It was discovered by AndrLouis Cholesky for real matrices. When it is applicable, the Cholesky decomposition is roughly twice asCompute the base2 logarithm of each element of x. If called with two output arguments, split x into binary mantissa and exponent so that 12 abs(f) 1 and e is an integer. If x 0, f square root of a matrix octave

If A is a matrix, then the elementwise square root is A. 0. 5. Use sqrt function for sqare root. I think you are femilier with loop. By using loops just pick eatch element in the matrix and apply sqrt. octave: 1 help sqrt sqrt is a builtin function Mapping Function: sqrt (X) Compute the square root of X. If X is negative, a complex result is returned. To compute the matrix square root, see Note Linear Algebra: : . Additional help for builtin functions, operators, and variables is**square root of a matrix octave** The power series expression for the square root on the eigenspace show that the principal square root of A has the form q(A) where q(t) is a polynomial with real coefficients. By DenmanBeavers iteration. Another way to find the square root of an n n matrix A is the DenmanBeavers square root iteration.
