STComputeExplicitOperator
Computes the explicit operator associated to the eigenvalue problem with the specified spectral transformation.
Synopsis
#include "slepcst.h"
PetscErrorCode STComputeExplicitOperator(ST st,Mat *mat)
Collective on ST
Input Parameter
st - the spectral transform context
Output Parameter
mat - the explicit operator
Notes
This routine builds a matrix containing the explicit operator. For
example, in generalized problems with shift-and-invert spectral
transformation the result would be matrix (A - s B)^-1 B.
This computation is done by applying the operator to columns of the
identity matrix. This is analogous to MatComputeExplicitOperator().
