PetscViewerMatlabOpen

 Opens a Matlab .mat file for output

Synopsis

PetscErrorCode  PetscViewerMatlabOpen(MPI_Comm comm,const char name[],PetscFileMode type,PetscViewer *binv)
Collective on MPI_Comm

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

Note: 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.
