Raise warning from simulink block mask initialization?

Hi,

From the mask initialization tab I am trying to check the value of a variable. If var == 999 I want to raise a warning. i.e. I want a warning to be shown in the Matlab command line. But using warning('message') or error('message') does nothing. Any ideas on how to do this? Thanks!

Hi Carlos,

Can you try using evalin('base', 'warning(''message'')') to see if that helps ?

Thanks for the suggestion Sreeram, but that did not work. For sending error messages this works:

try
    if var == 999
        error('error message')
    end
catch exception
    throwAsCaller(exception)
end

but I still don't ave a solution for warnings.

Actually that works Sreeram, but not as well as I would like. If I write the evalin('base','warning(''meassage'')') command in the mask initialization it works perfectly.

But to keep the question simple I had omitted some details. I need to call the same error checking from 11 different blocks in my library. So ideally I'd like this little piece of code to be a function (class method actually). If I put the evalin(...) in a class method and then call that method from the block initialization then it does not work.

I'd prefer it to be a class method so that I do not have to change it in 11 different places when I want to make a change.

Any idea on how to do this?

Thanks for the help!

Can you try an feval combination with evalin ?

For example evalin('base', 'feval(''warning_function_class'', ''parameters'')')

Just a thought !
