Fixed Point Tool not working with Matlab Function Block in Simulink

Hello everyone,
I have a rather simple model containing two Matlab function blocks with the following code:
function valueAtIndex = fcn(tappedDelays, index)
% Extracts the value of a vector signal at a specified index.
valueAtIndex = tappedDelays(index);
Now I'm trying to use the Simulink Fixed-Point Tool to derive an appropriate fixed-point representation of the model.
However, the Fixed-Point Advisor keeps telling me that my system contains blocks that do not support fixed-point data types and lists the MATLAB function blocks I mentioned above.
How can that be? In the Model Explorer, I can without any problems specify my function to take fixed-point arguments, therefore I'd say the error message is plain nonsense!
What I wanted to do is let the Fixed-Point Advisor propose optimal fixed-point types to me. Is there any possibility to have it do so?
Kind Regards and thanks in advance,
Eike
