MatSolve

 Solves A x = b, given a factored matrix.

Synopsis

#include "petscmat.h" 
PetscErrorCode MatSolve(Mat mat,Vec b,Vec x)
Neighbor-wise Collective on Mat

Input Parameters

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

Output Parameter

x -the result vector

Notes

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