Hi @ all,
I would like to use some variables defined in a m-file into embedded Matlab block in Simulink. I would like to do this without define again the variables names and values.
Someone knows if it possible to use some global variables defined in the Matlab workspace in the embedded Matlab block in Simulink?
There is an alternative method to do what I want?
Thanks in advance
Mitch

Please do not pass a Constant to a MATLAB Function block using a signal... you should pass the value as a parameters:

Thanks Azzi and Guy,
@ Azzi I already use constant block but when there are a lot of parameters is not confortable.
@ Guy Your help was very usefull. How can I accpet your answer?

I've always used constant block as input argument for Matlab function block and it worked fine. But I 've also thought that there is a better way to do it, Guy 's answer is really what I was looking for. Thanks Guy
