VecMTDot

Computes indefinite vector multiple dot products. That is, it does NOT use the complex conjugate.

#include "petscvec.h" 
int VecMTDot(int nv,Vec x,const Vec y[],PetscScalar *val)

Collective on Vec

	nv	- number of vectors
	x	- one vector
	y	- array of vectors. Note that vectors are pointers

val -array of the dot products

For complex vectors, VecMTDot() computes the indefinite form

     val = (x,y) = y^T x,

where y^T denotes the transpose of y.

Use VecMDot() for the inner product

     val = (x,y) = y^H x,

where y^H denotes the conjugate transpose of y.
