STInnerProduct

Computes the inner product of two vectors.

Synopsis

#include "slepcst.h" 
PetscErrorCode STInnerProduct(ST st,Vec x,Vec y,PetscScalar *p)
Collective on ST and Vec

Input Parameters

st - the spectral transformation context
x - input vector
y - input vector

Output Parameter

p - result of the inner product

Notes

This function will usually compute the standard dot product of vectors x and y, (x,y)=y^H x. However this behaviour may be different if changed via STSetBilinearForm(). This allows use of other inner products such as the indefinite product y^T x for complex symmetric problems or the B-inner product for positive definite B, (x,y)_B=y^H Bx.
