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 Many br

Input Parameters

comm - MPI communicator Many br
name - name of file Many br
type - type of file Many br
   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 Many br

Many br

Note: This PetscViewer should be destroyed with PetscViewerDestroy(). Many br

For writing files it only opens the file on processor 0 in the communicator. Many br

This only saves Vecs it cannot be used to save Mats. We recommend using the PETSCVIEWERBINARY to save objects to be loaded into MATLAB Many brinstead of this routine. Many br
