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.
