EPSVectorsView#
Outputs computed eigenvectors to a viewer.
Synopsis#
#include "slepceps.h"
PetscErrorCode EPSVectorsView(EPS eps,PetscViewer viewer)
Collective
Input Parameters#
eps - the linear eigensolver context
viewer - the viewer
Options Database Key#
-eps_view_vectors - output eigenvectors
Notes#
If PETSc was configured with real scalars, complex conjugate eigenvectors will be viewed as two separate real vectors, one containing the real part and another one containing the imaginary part.
If left eigenvectors were computed with a two-sided eigensolver, the right
and left eigenvectors are interleaved, that is, the vectors are output in
the following order: X0, Y0, X1, Y1, X2, Y2, ...
The command-line option listed above admits an optional argument
specifying the viewer type and options. For instance, use
-eps_view_vectors binary:evecs.bin to save the vectors in a binary file.
