MatMultTranspose

Computes matrix transpose times a vector.

Synopsis

#include "petscmat.h" 
PetscErrorCode  MatMultTranspose(Mat mat,Vec x,Vec y)
Neighbor-wise Collective on Mat and Vec

Input Parameters

mat - the matrix
x - the vector to be multilplied

Output Parameters

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()
