MatMultTranspose#
Computes matrix transpose times a vector y = A^T * x.
Synopsis#
#include "petscmat.h"
PetscErrorCode MatMultTranspose(Mat mat, Vec x, Vec y)
Neighbor-wise Collective
Input Parameters#
mat - the matrix
x - the vector to be multiplied
Output Parameter#
y - the result
Notes#
The vectors x and y cannot be the same. I.e., one cannot
call MatMultTranspose(A,y,y).
For complex numbers this does NOT compute the Hermitian (complex conjugate) transpose multiple,
use MatMultHermitianTranspose()
