Using Cholesky decomposition to solve a system of equaions

WebMar 14, 2024 · To solve using matrix math you multiply the left side using the inverse of the 4x4 matrix placed to the far left. And do the same to the right side, also placing the inverse to the left. So Y − 1 Y V = Y − 1 I. Then just perform the right side multiplication. Or by hand use Cramer's Rule. WebIff a symmetric matrix ‘A’ is positive definite, then an upper triangular matrix ‘R’ (Cholesky’s factor) exists such that ‘A = RTR’ (using Cholesky’s factorisation). - This can be used to factorise matrices using lesser number of flops.
