This is a test:
if i == D(k)
It is the correct way to use == because == is a comparison operator.
However, this other line is an assignment. That is, you are calling the function max, and returning a result in the variable i.
[~, i] == max(y);
The error mesage about ~ that you report is confusing to you. The problem is, MATLAB was also confused, because you used invalid syntax there. So MATLAB generated whatever error it could. The correct syntax to perform an assignment uses a SINGLE = operator, thus:
[~, i] = max(y);
