Hi,

I have a S-Function block that is masked. In the mask, I have defined a mask parameter called 'sigConv'. I am using this parameter in the S-Function parameters field by inserting "['sFuncVar=',sigConv]"

What I want to do: I want to achieve the same, that happens when I change the value in the mask and click "ok" after that. But from an m-file.

But when I use the set_param() function, I can only change the value in the mask, but it's not forwarded to the S-Function block.

The documentation says in the chapter "Programming Masks Programmatically":
"However, changing the mask parameter value with set_param does not change the value of the underlying block variable. You cannot use get_param or set_param to access the value of the underlying variable, because it is hidden by the mask."

But how can I change this underlying variable?

Regards,

Andreas
