<div dir="ltr">I learned users should call KSPGetConvergedReason to check if a KSPSolve was successful. But if users directly call MatSolve() or MatMatSolve etc, how can they know it was successful?
<div>I see in MatSolve_MUMPS, it first checks factor errors. If there is, it sets the solution to infinity; But it does not do that in MatMatSolve. Also, in MatSolve_MUMPS, if the factorization was fine but the solve failed, the code just aborts. Is it wrong
in a KSP context?</div>
