This example shows how to attach an engine program to a MATLAB® session that is already running.
On a Windows® platform, start MATLAB with
-automation in the command line. When you call
engOpen, it connects to this existing session. You should only call
engOpen once, because any
engOpen calls now
connect to this one MATLAB session.
-automation option also causes the command window to be
minimized. You must open it manually.
On the Mac and Linux® platforms, you cannot make an engine program connect to an existing MATLAB session.
Shut down any MATLAB sessions.
From the Start button on the Windows menu bar, click Run.
In MATLAB, capture the value returned by the command:
path = fullfile(matlabroot,'bin',computer('arch'))
In the Run dialog box Open
field, type the following command, replacing
path with the
value from the previous step:
Click OK. This starts MATLAB.
In MATLAB, copy the
engwindemo.c example to a writable
Build the example.
mex -client engine engwindemo.c
engwindemo program by typing at the MATLAB prompt:
This does not start another MATLAB session, but rather uses the MATLAB session that is already open.
