PETSC_VIEWER_SOCKET_

Creates a socket viewer shared by all processors in a communicator.

PetscViewer  PETSC_VIEWER_SOCKET_(MPI_Comm comm)

Collective on MPI_Comm

comm -the MPI communicator to share the socket PetscViewer

For use with the default PETSC_VIEWER_SOCKET_WORLD or if NULL is passed for machine or PETSC_DEFAULT is passed for port

   -viewer_socket_machine <machine>

   -viewer_socket_port <port>

Unlike almost all other PETSc routines, PetscViewer_SOCKET_ does not return an error code. The socket PetscViewer is usually used in the form

      XXXView(XXX object,PETSC_VIEWER_SOCKET_(comm));

Currently the only socket client available is MATLAB. See src/dm/examples/tests/ex12.c and ex12.m for an example of usage.

Connects to a waiting socket and stays connected until PetscViewerDestroy() is called.

Use this for communicating with an interactive MATLAB session, see PETSC_VIEWER_MATLAB_() for writing output to a .mat file. Use PetscMatlabEngineCreate() or PETSC_MATLAB_ENGINE_(), PETSC_MATLAB_ENGINE_SELF, or PETSC_MATLAB_ENGINE_WORLD for communicating with a MATLAB Engine
