I am using a masked m-File in Simulink where I use a filed ParamName. This ParmName contains a string which is giving the name of a structure in the workspace. E.g. ParamName 'Test' in the workspace I would have a structure like Test.Val: uint16 value Test.DebVal: uint16 value Test.DebMethod: string How can I change the values of Test in the m-function? The parameter I can access in the m-function is ParamName, but it is not possible to have a command like 'ParamName.Val=12;' which would set Test.Val=12.

Not sure to get you problem.

You want to create a masked block and Initialize it with a script ?

Something like ?

In principal yes. The Subsystem would be a m-Script. The name of the structure could be changed by user since the function would be used for different variables.

The Subsystem would be a m-Script

Do you mean a Matlab Function block ?

In all cases, whatever the content of your subsystem is, when you define a mask, you can reuse your block with a differaent parameter, that's the purpose of masks.

With the block I attached, just by pasting it and by defining a new variable, I get :
