MatSolves

 Solves A x = b, given a factored matrix, for a collection of vectors

Synopsis

#include "petscmat.h" 
PetscErrorCode MatSolves(Mat mat,Vecs b,Vecs x)
Neighbor-wise Collective on Mat and Vecs

Input Parameters

mat - the factored matrix
b - the right-hand-side vectors

Output Parameter

x -the result vectors

Notes

The vectors b and x cannot be the same. I.e., one cannot call MatSolves(A,x,x).

Notes

Most users should employ the simplified KSP interface for linear solvers instead of working directly with matrix algebra routines such as this. See, e.g., KSPCreate().
