PetscViewerMatlabOpen#
Opens a MATLAB .mat file for output
Synopsis#
#include "petscviewer.h"
#include "petscmat.h"
PetscErrorCode PetscViewerMatlabOpen(MPI_Comm comm, const char name[], PetscFileMode type, PetscViewer *binv)
Collective
Input Parameters#
comm - MPI communicator
name - name of file
type - type of file
FILE_MODE_WRITE - create new file for MATLAB output
FILE_MODE_READ - open existing file for MATLAB input
FILE_MODE_WRITE - open existing file for MATLAB output
Output Parameter#
binv - PetscViewer for MATLAB output to use with the specified file
Notes#
This PetscViewer should be destroyed with PetscViewerDestroy().
For writing files it only opens the file on processor 0 in the communicator.
This only saves Vecs it cannot be used to save Mats. We recommend using the PETSCVIEWERBINARY to save objects to be loaded into MATLAB
instead of this routine.
PETSc must be configured with the option --with-matlab for this functionality
