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 input/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. For readable files it opens the file on all nodes that have the file. If node 0 does not have the file it generates an error even if other nodes do have the file.
