The { } formulation for blocking code is not valid MATLAB syntax. To fix this:

• Get rid of the open brace {
• Replace the close brace } with end

I.e., instead of

if something
    {
    stuff;
    }

Do this

if something
    stuff;
end

In addition to what James wrote, this syntax doesn't do what I believe you think it does.

if 0<=u<=(pi/3)

If you open that file in the MATLAB Editor, you should see a Code Analyzer message on those lines explaining what it does and how to do what you want. I believe there may even be an auto-fix available.
