Summary description: Draw colored represenations of complex functions
Announcement text: ----------------------------------------------------------------------
Domain coloring is a technique to visualize complex functions by assigning a color to each point of the complex plane z=x+iy. This package caculates with the help of Lua any complex function to visualize its behaviour. The value of the complex function(z) can be described by radius and angle which can be two values of the hsv-color model, which then defines the color of each point in the complex plane z=x+iy.
