Hi all,
I am dealing with a problem with cholesky factorization lately. Since the computation speed of cholmod is quite fast, I decided to use CholmodSuport module. However, I had a problem that I could not find a way to get L matrix directly, which was available with old CholmodSuport API.
So, my question is: how can I get the L matrix with the new CholmodSuport? Any suggestions would be greatly appreciated
Thanks~

Indeed, it seems this feature disappeared. I don't remember if there was a good reason for that but adapting the old matrixL() function to the new code should be quite easy. In the meantime you might try to come up with a patch yourself or use ou built-in SimplicialLDLT (or SimplicialLLT). If you are dealing with 2D problems it should give you very good performance as well.
