BVMatMultTranspose#

Computes the matrix-vector product with the transpose of a matrix for each column, \(Y=A^T V\).

Synopsis#

#include "slepcbv.h" 
PetscErrorCode BVMatMultTranspose(BV V,Mat A,BV Y)

Neighbor-wise Collective

Input Parameters#

  • V - basis vectors context

  • A - the matrix

Output Parameter#

  • Y - the result

Notes#

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 MatCreateTranspose().
