#include "petscvec.h" PetscErrorCode VecView(Vec vec,PetscViewer viewer)Collective on Vec Many br
vec | - the vector Many br | |
viewer | - an optional visualization context Many br |
PETSC_VIEWER_STDOUT_SELF | - for sequential vectors Many br | |
PETSC_VIEWER_STDOUT_WORLD | - for parallel vectors created on PETSC_COMM_WORLD Many br | |
PETSC_VIEWER_STDOUT_(comm) | - for parallel vectors created on MPI communicator comm Many br |
You can change the format the vector is printed using the Many broption PetscViewerPushFormat(). Many br
The user can open alternative visualization contexts with Many br
PetscViewerASCIIOpen() | - Outputs vector to a specified file Many br | |
PetscViewerBinaryOpen() | - Outputs vector in binary to a Many brspecified file; corresponding input uses VecLoad() Many br | |
PetscViewerDrawOpen() | - Outputs vector to an X window display Many br | |
PetscViewerSocketOpen() | - Outputs vector to Socket viewer Many br |
The user can call PetscViewerPushFormat() to specify the output Many brformat of ASCII printed objects (when using PETSC_VIEWER_STDOUT_SELF, Many brPETSC_VIEWER_STDOUT_WORLD and PetscViewerASCIIOpen). Available formats include Many br
PETSC_VIEWER_DEFAULT | - default, prints vector contents Many br | |
PETSC_VIEWER_ASCII_MATLAB | - prints vector contents in MATLAB format Many br | |
PETSC_VIEWER_ASCII_INDEX | - prints vector contents, including indices of vector elements Many br | |
PETSC_VIEWER_ASCII_COMMON | - prints vector contents, using a Many brformat common among all vector types Many br |
Notes: You can pass any number of vector objects, or other PETSc objects to the same viewer. Many br
Notes for binary viewer: If you pass multiply vectors to a binary viewer you can read them back in in the same order Many br
with VecLoad().
If the blocksize of the vector is greater than one then you must provide a unique prefix to
the vector with PetscObjectSetOptionsPrefix((PetscObject)vec,"uniqueprefix"); BEFORE calling VecView() on the
vector to be stored and then set that same unique prefix on the vector that you pass to VecLoad(). The blocksize
information is stored in an ASCII file with the same name as the binary file plus a ".info" appended to the
filename. If you copy the binary file, make sure you copy the associated .info file with it.
Notes for HDF5 Viewer: the name of the Vec (given with PetscObjectSetName() is the name that is used Many br
for the object in the HDF5 file. If you wish to store the same vector to the HDF5 viewer (with different values,
obviously) several times, you must change its name each time before calling the VecView(). The name you use
here should equal the name that you use in the Vec object that you use with VecLoad().
See the manual page for VecLoad() on the exact format the binary viewer stores Many brthe values in the file. Many br
