IPMInnerProduct
Computes the inner products a vector x with a set of vectors (columns of Y).
Synopsis
#include "slepcip.h"
PetscErrorCode IPMInnerProduct(IP ip,Vec x,PetscInt n,const Vec y[],PetscScalar *p)
Collective on IP and Vec
Input Parameters
| ip | - the inner product context
|
| x | - the first input vector
|
| n | - number of vectors in y
|
| y | - array of vectors
|
Output Parameter
p - result of the inner products
Notes
This function will usually compute the standard dot product of x and y_i,
(x,y_i)=y_i^H x, for each column of Y. However this behaviour may be different
if changed via IPSetMatrix(). This allows use of other inner products
such as the indefinite product y_i^T x for complex symmetric problems or the
B-inner product for positive definite B, (x,y_i)_B=y_i^H Bx.
