Plotting tools for complex-valued functions
Project description
cplot
Plotting complex-valued functions.
cplot is an attempt at encoding complex-valued data in colors. The general idea is to map the absolute value to lightness and the complex argument (the "angle") to the chroma of the representing color.
The representation is chosen such that
- values around 0 are black,
- values around infinity are white,
- values around +1 are green,
- values around -1 are red,
- values around +i are blue, and
- values around -i are yellow.
See below for examples with some well-known functions.
import cplot
import numpy
cplot.show(numpy.tan, -5, +5, -5, +5, 100, 100)
# There is a tripcolor function as well for triangulated 2D domains
# cplot.tripcolor(triang, z)
z**1 | z**2 | z**3 |
1/z | (z+1) / (z-1) | (z-1) / (z+1) |
numpy.sin | numpy.cos | numpy.tan |
numpy.exp | numpy.log | scipy.special.gamma |
