VecMDot

Computes vector multiple dot products.

Synopsis

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

Input Parameters

nv - number of vectors
x - one vector
y - array of vectors.

Output Parameter

val -array of the dot products

Notes for Users of Complex Numbers

For complex vectors, VecMDot() computes
    val = (x,y) = y^H x,
where y^H denotes the conjugate transpose of y.

Use VecMTDot() for the indefinite form

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