How to get Solver type when performing \ operation
显示 更早的评论
I am solving a least squares system of equations with x=A\b. Matrix A should be a positive semi-definite sparse matrix that needs to be solved with Cholesky.
However, at the inital step it has a negative eigenvalue and Matlab switch solver internally in order to find a solution. After this initial step, all the eigenvalues switch to positve and the system is finally positive semi-definite, I think that here Cholesky takes place.
Is there anyway to see what is the solver that Matlab is using when performing the \ operation?

See mldivide documentation, there's an algorithm shown there.
