Event MatlabManager

This MATLAB plug-in allows the user to connect to and use the MATLAB Engine.

Note to user: There are some functions/toolkits that MATLAB does not support integration with C or fortran, or on some operating platforms. So check with MATLAB documentation before using the plug-in.

There a 2 ways to use the MATLAB plug-in:- The first (legacy) way is to route the *Request() events and setup listeners for the *Response() events. If you are only using the plug-in from the main context, injecting MatlabService.mon will setup all the required listeners for the *Request() events which call through to the plug-in. If you wish to use the plug-in from another context, you will have to instantiate a MatlabManager variable and call #initialize() on it after the spawn to the new context. This will set up the required listeners in the current (non-main) context, and the *Response() events will be routed to this context. The second way is to use the MatlabManager event itself, and call the relevant action and supply a callback. This way saves routing the request event as the call goes directly to the plug-in. However, the *Response() events are still routed from the plug-in to the calling context. The request actions automatically set-up a listener for the *Response() event which will call the supplied callback. You can supply the relevant doesNothing*Callback() from MatlabManager if you are not interested in the results of the callback. If you use the MatlabManager actions you do not need to call #initialize().

The MATLAB plug-in is asynchronous (except the OpenSession requests) so the processing of the input queue, or calling the request actions, does not block.

It is also multi-context aware, the *Response() events are routed to the calling context.
