If matrix A is positive definite and symmetric. Can I use cholesky Factorization to find the square root of A?
:by cholesky factorization ,A=LDL' where L is a low triangular matrix ,D is diagonal matrix, then square root of A is Ld where d is the matrix which square root all the term in D.
Is it correct?
Is there an algorithm for finding square root of A which is not symmetric?
