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;
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:
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?
