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

Input Parameters#

x - first vector
y - second vector

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.
