VecTDot

Computes an indefinite vector dot product. That is, this routine does NOT use the complex conjugate.

Synopsis

#include "petscvec.h"   
PetscErrorCode  VecTDot(Vec x,Vec y,PetscScalar *val)
Collective on Vec

Input Parameters

x, y -the vectors

Output Parameter

val -the dot product

Notes for Users of Complex Numbers

For complex vectors, VecTDot() computes the indefinite form
    val = (x,y) = y^T x,
where y^T denotes the transpose of y.

Use VecDot() for the inner product

    val = (x,y) = y^H x,
where y^H denotes the conjugate transpose of y.
