MatSolveTranspose

Solves A' x = b, given a factored matrix.

Synopsis

#include "petscmat.h" 
PetscErrorCode  MatSolveTranspose(Mat mat,Vec b,Vec x)

Neighbor-wise Collective on Mat and Vec

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 MatSolveTranspose(A,x,x).

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().
