Hi,
I have a c++ file with octave embedded in it. Calculating via Matrices and
so on works fine but I don't get it how do I use functions, e.q. the fft in
c++ / upon variables from/in c++ ?
The documentation
https://www.gnu.org/software/octave/doc/v4.0.1/Signal-Processing.html just
tells fft(x).
Just briefly: I have an array in c++ and I want to apply fft on it. How do I
do that?
Thank you very much!
