I have a simple m file function that adds 2 vectors, just to get the code generator to generate neon code,
but there are no calls to neon in the generated code.
This is the function:
function y = simple_addition(u1,u2)
%#codegen
% Copyright 2015 The MathWorks, Inc.
y = u1 + u2;
end
The image below shows captures from the process

Hi Barry,
In addition to setting the hardware setting you also need to change the "Code Replacement Library" settings from "More Settings>Custom Code".
You can find an example that demonstrates the overall process below:

Hope this helps
