Can MATLAB Fcn block output a bus?

I'm trying to use MATLAB Fcn block to output a bus. I can't use an Embedded MATLAB Fcn block for reasons that I would rather not get into now.

Does anyone knows how to do this?

I don't know your reasons for not wanting to use an Embedded MATLAB function block, but that would be my recommendation. It can output a bus and because it uses code generation, is very efficient. A MATLAB Fcn block, on the other hand, calls the MATLAB parser during each integration step and therefore is very inefficient. I would avoid using it if at all possible.

[Davide Ferraro]

The MATLAB function block is not able to create a bus.

We strongly suggest the use of the Embedded MATLAB function that allows better performances and code flexibility. If you can express your doubts regarding the use of the Embedded MATLAB function we may provide you further assistance.

Are you aware of the eml.extrinsic command? http://www.mathworks.com/access/helpdesk/help/toolbox/eml/ref/eml.extrinsic.html

This command allows you to use any function (not necessarily from Embedded MATLAB subset). This reduces the performance (and is not working for code generation) but allows you to use all MATLAB features.

Thanks for the response! I came to the same conclusion and used eml.extrinsic command. Although from your answer it seems that I can't use it for my application. The simulink code i'm working on essential goes into an embedded target.
