Can't use any of that, because they all use complex.h (not supported by my compiler) and I have an interleaved array of complex numbers where 0 = real, 1 = imag, 2 = real, 3 = imag etc.

Dear ProbablyRealPersonGPT, please provide the necessary code in C with a short explanation

It must be old or weird, then. I thought older versions of MSVC were the only C compilers in real use that didn't support it?

That's another thing I like about ChatGPT. It doesnt judge my compiler ;)
