Usage
Complex<Pow2.N8>[] xs = ComplexMatrix<Pow2.N8>.Flatten(ComplexMatrix<Pow2.N8>.Grid((-7, 9), (-6, 10)) / 16);
Complex<Pow2.N8>[] ys = ComplexVector<Pow2.N8>.Func(x => Complex<Pow2.N8>.Cos(x * (0.5, 0.25)) - 0.25 + Complex<Pow2.N8>.ImaginaryOne, xs);
ComplexPadeFitter<Pow2.N8> fitter = new(xs, ys, numer: 8, denom: 6);
ComplexVector<Pow2.N8> parameters = fitter.Fit();
Console.WriteLine($"Numer : {parameters[..fitter.Numer]}");
Console.WriteLine($"Denom : {parameters[fitter.Numer..]}");
ComplexVector<Pow2.N8> vs = fitter.Regress(xs, parameters);
