PetscStartMatlab - starts up MATLAB with a MATLAB script
Logically Collective on MPI_Comm, but only processor zero in the communicator does anything
Input Parameters:

. machine - optional machine to run MATLAB on
- script - name of script (without the .m)
Output Parameter:
. fp - a file pointer returned from PetscPOpen()
Level: intermediate
Notes:
This overwrites your matlab/startup.m file
The script must be in your MATLAB path or current directory
Assumes that all machines share a common file system

/*@C
PetscEmacsClientErrorHandler - Error handler that uses the emacsclient program to
load the file where the error occured. Then calls the "previous" error handler.
Not Collective
Input Parameters:
+ comm - communicator over which error occured
. line - the line number of the error (indicated by __LINE__)
. func - the function where error is detected (indicated by __FUNCT__)
. file - the file in which the error was detected (indicated by __FILE__)
. dir - the directory of the file (indicated by __SDIR__)
. mess - an error text string, usually just printed to the screen
. n - the generic error number
. p - specific error number
- ctx - error handler context
Options Database Key:
. -on_error_emacs <machinename>
Level: developer
Notes:
You must put (server-start) in your .emacs file for the emacsclient software to work
Most users need not directly employ this routine and the other error
handlers, but can instead use the simplified interface SETERRQ, which has
the calling sequence
$ SETERRQ(PETSC_COMM_SELF,number,p,mess)
Notes for experienced users:
Use PetscPushErrorHandler() to set the desired error handler.
Developer Note: Since this is an error handler it cannot call CHKERRQ(); thus we just return if an error is detected.
Concepts: emacs^going to on error
Concepts: error handler^going to line in emacs
