Graph complex functions using hsv colors.
The idea here is we graph the inputs on a normal plane, and then the outputs using hue and saturation (polar: hue = theta, sat = r). Perhaps more robust systems exist; I'm not well versed in the study of complex functions, but maybe this will be helpful.
Currently you need to change the definition of fn in src/Run.hs to change the graph.
You can run the program with stack run -- complex-hsv-exe -v.
The program has a few command line options; the most important are -r RES, where RES is the number of pixels on the side of the image, -i (MINA,MAXA,MINB,MAXB), which specifies the window size MATLAB-style, and -o FILENAME.png, which specifies where to save the graph image. You can see the rest of the options by running stack run -- complex-hsv-exe --help.
f(z) = z:
f(z) = z**2:
f(z) = e**z:
f(z) = ln z. N.B. in the complex worldexpis non-invertible:
