BVMatMultHermitianTranspose
Computes the matrix-vector product with the conjugate transpose of a matrix for each column, Y=A^H*V.
Synopsis
#include "slepcbv.h"
PetscErrorCode BVMatMultHermitianTranspose(BV V,Mat A,BV Y)
Neighbor-wise Collective
Input Parameters
| V | - basis vectors context
|
| A | - the matrix
|
Output Parameter
Note
Both V and Y must be distributed in the same manner. Only active columns
(excluding the leading ones) are processed.
In the result Y, columns are overwritten starting from the leading ones.
The number of active columns in V and Y should match, although they need
not be the same columns.
Currently implemented via MatCreateHermitianTranspose().
