PetscViewerMatlabOpen#

Opens a MATLAB .mat file for output

Synopsis#

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
