BVApplyMatrixBV

Multiplies the BV vectors by the matrix representation of the inner product.

Synopsis

#include "slepcbv.h" 
PetscErrorCode BVApplyMatrixBV(BV X,BV Y)
Neighbor-wise Collective

Input Parameter

X  - the basis vectors context

Output Parameter

Y  - the basis vectors to store the result (optional)

Note

This function computes Y = B*X, where B is the matrix given with BVSetMatrix(). This operation is computed as in BVMatMult(). If no matrix was specified, then it just copies Y = X.

If no Y is given, the result is stored internally in the cached BV.
