Re: [petsc-users] MUMPS error reporting in PETSc-3.7

David, Actually all the routines for accessing the MUMPS information already exist. I have added this to the manual page for MATSOLVERMUMPS Notes: When a MUMPS factorization fails inside a KSP solve, for example with a KSP_DIVERGED_PCSETUP_FAILED, one can find the MUMPS information

Re: [petsc-users] Functionality in Petsc

Assuming that you don't want to store this dense rank-1 matrix explicitly, one way to go is to define your own MATSHELL which holds your two vectors and can apply the outer product to a vector. > Am 06.06.2016 um 19:49 schrieb Sophie Léger : > > Hello, > > I’m

[petsc-users] Functionality in Petsc

Hello, I'm trying to multiply a column vector with a line vector (which would result in a matrix) and am wondering if this is possible with Petsc? I have looked, but have not found anything yet. Would it be possible to let me know if such a functionality exists and if so guide me in the right
