Summary[edit]
| Description |
English: This image was created with mayavi2.
This is the python code I used to create the image: from numpy import *
from enthought.mayavi import mlab
def complex_plot(function,
maxval=9,
xbounds=(-3.0,3.0),
ybounds=(-3.0,3.0),
stepsize=0.01,
text="",
textwidth=0.1,
unitcylrange=(-4,4),
zmax=9,
zmin=-9,
legend=True,
signed=True):
try:
engine = mayavi.engine
except NameError:
from enthought.mayavi.api import Engine
engine = Engine()
engine.start()
f=mlab.figure(fgcolor=(0, 0, 0), bgcolor=(1, 1, 1), size=(500,500))
x,y = mgrid[xbounds[0]:xbounds[1]:stepsize, ybounds[0]:ybounds[1]:stepsize]
if signed:
z = maximum(minimum(abs(function(x+y*1j))*sign(real(function(x+y*1j))), zmax), zmin)
else:
z = maximum(minimum(abs(function(x+y*1j)), zmax), zmin)
s = angle(function(x+y*1j))
m=mlab.mesh(x,y,z, scalars=s)
from enthought.mayavi.modules.axes import Axes
axes = Axes()
engine.add_filter(axes, m.module_manager)
mlab.text(0, 0, text, width=textwidth)
phi, v=mgrid[0.0:2.01*pi:0.1, unitcylrange[0]:unitcylrange[1]:0.1]
mlab.mesh(cos(phi),sin(phi),v, color=(1,1,1), opacity=0.5)
if legend:
mlab.colorbar(title="phase", orientation='vertical')
complex_plot(lambda x: (x**2-1) * (x-2-1j)**2 / (x**2+2+2j), zmin=-5, zmax=30, xbounds=(-2.25,5), ybounds=(-3,4), unitcylrange=(-0.001,0), signed=False, stepsize=0.01)
