How to pass mask parameters in a child Matlab function ?

5 views (last 30 days)
Hello everyone,
In my model, I created a masked subsystem with many parameters (around 90 parameters). In this subsystem, I introduced a Matlab function and I need to use the parameters I defined earlier in the parent-subsystem mask to resolve equations.
The content of the parent masked-subsystem is represented in the screenshot below :
The yellow blocks correspond to blocks which use a parameter from the mask upper in the block hierarchy and these parameters are recognized. However, they're not in the Matlab function.
I looked on the help center but no topics correspond to the issue I'm encountering. I don't want to create a mask for the Matlab function with the same parameters or to add around 90 constant blocks grouped by a bus to send it to the Matlab function.
So, here is my question : why does Matlab function not recognize the mask parameters ?
I kindly thank you in advance for your answers,
Best regards
AS

For those yellow blocks or any of the typical Simulink blocks, there is a block parameter dialog, where you can specify a variable for a parameter. This variable is usually defined in workspace, but you can mask it and provide its value through mask dialog. This is how mask works.
So you need to add a "parameter" to the MATLAB Function. Click "edit data" button at the Editor, add a data and specify it as "parameter".

Well, I should have masked the Matlab function in place of the parent subsystem. It's good to know, thank you for your reply.
There is, indeed, 80 parameters but they are not used all the time so I masked the parameters useless in some case and use tabs to make the mask easily readable by the user.
