This demonstration evolves a simplified version of the Complex Ginzburg Landau equation.

Plot type 1 shows the magnitude of the complex field is plotted on a gray scale minimum-maximum = black-white.
Plot type 2 shows the phase angle plotted on a "rainbow" color plot 0-90-180-270-360 = red-yellow-green-blue-red.

It is interesting to study how the dynamics depends on the parameter c₃, e.g. try values 0.5, 1.25, 2.5.

You can find the same demonstration but in a system size twice as large in demonstration 2.
