    Xi = fft(xi);
    spec(:,i) = Xi(1:winLenHalf+1); % This line is occured error when convert to C++.
end

I convert to C++ use matlab coder so, occured below error message.

[problem code below]

spec(:,i) = Xi(1:winLenHalf+1);

[error message]

The left-hand side has been constrained to be non-complex, but the right-hand side is complex. To correct this problem, make the right-hand side real using the function REAL, or change the initial assignment to the left-hand side variable to be a complex value using the COMPLEX function.

[question]

How do I convert like a same matlab without loss original wav sound file?

I tried two method in error message but not same convert.
