VecTDot

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

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

Collective on Vec

x, y -the vectors

val -the dot product

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.
