Hello,
I have simple simulink model with a single constant source, a user-function block and a scope sink.
The function is defined by
function y = fcn(u)
y = A*u;
end
where the variable A=1 is defined in the base workspace and in the model workspace as well.
When clicking on "Explore" in simulink, one can see the variable A in the workspaces.
However, when running the simulink model, I get the following error
Undefined function or variable 'A'.
Function 'MATLAB Function' (#46.24.25), line 2, column 5:
"A"
The current folder is set in the path and I am using Ubuntu 18.04.
No settings changes to the default installation were made and restarting matlab did not solve the issue.
What could be the reason for this behaviour?

You need to add "A" as a parameter for the MATLAB Function block.
Double click to open the "MATLAB Function" block editor, click "Edit Data", menu "Add", "Data", add data "A" and specify the scope as "parameter".
