2013-10-10 09:57:38 -0600	asked a question	Cholesky decomposition with OpenCV Hi there, I have a prolem using the Cholesky decomposition in OpenCV. I have the positive definite matrix A with A = `8312069 34511.344 -306.38861 34511.313 8231020.5 -112.6131 -306.38861 -112.6131 1` The function call `Mat L = A.inv(DECOMP_CHOLESKY)` should give me the Matrix L, which satisfies `A = LL'`. However, I'm getting a matrix with awkwardly small values and for which `A = LL'` does not hold. What could there possibly be wrong, the usage is dead simple ... ?? (The decomposition of A works fine in MATLAB).
