MatSolveTransposeAdd#
Computes \(x = y + A^{-T} b\) factored matrix.
Synopsis#
#include "petscmat.h"
PetscErrorCode MatSolveTransposeAdd(Mat mat, Vec b, Vec y, Vec x)
Neighbor-wise Collective
Input Parameters#
mat - the factored matrix
b - the right-hand-side vector
y - the vector to be added to
Output Parameter#
x - the result vector
Note#
The vectors b and x cannot be the same. I.e., one cannot
call MatSolveTransposeAdd(A,x,y,x).
