lab -a context to use when communicating with the server
Notes
Most users should employ the following commands to access the
MATLAB PetscViewers
PetscViewerSocketOpen(MPI_Comm comm, char *machine,int port,PetscViewer &viewer)
MatView(Mat matrix,PetscViewer viewer)
or
PetscViewerSocketOpen(MPI_Comm comm,char *machine,int port,PetscViewer &viewer)
VecView(Vec vector,PetscViewer viewer)
Options Database Keys
For use with PETSC_VIEWER_SOCKET_WORLD, PETSC_VIEWER_SOCKET_SELF,
PETSC_VIEWER_SOCKET_() or if
NULL is passed for machine or PETSC_DEFAULT is passed for port
-viewer_socket_machine <machine>
-viewer_socket_port <port>
Environmental variables
| PETSC_VIEWER_SOCKET_PORT portnumber | - - PETSC_VIEWER_SOCKET_MACHINE machine name
|
Currently the only socket client available is MATLAB. See
src/dm/examples/tests/ex12.c and ex12.m for an example of usage.
Notes: The socket viewer is in some sense a subclass of the binary viewer, to read and write to the socket
use PetscViewerBinaryRead(), PetscViewerBinaryWrite(), PetscViewerBinarWriteStringArray(), PetscViewerBinaryGetDescriptor().
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
