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).
