So far the tests:
The new tests contain cosine and sine functions with frequency shifts.
The forward Fourier Transform is about 40% done.
It still needs:
- Differential equations(important)
- Integral equations
- Amplitude modulation
- Special functions(e.g. cos(at^2))
- Frequency differentiation
- Frequency integration
It might be the last update for a while since I have other work to do.
