Complex Ginzburg Landau Equation

This demonstration studies the solves the Complex Ginzburg Landau equation introduced in Sections 5.4 and 10.2.2. The applet evolves a special form of the equation for the complex field A(x,y,t):
The most general form has a complex coefficient multiplying the derivative terms, but for ease of the numerics this has been chosen as unity. The coefficient (1-ic3) of the first term on the right hand side is chosen to make the appearance of the dynamics more consistent with our intuition on wave propagation - this coefficient can be changed arbitrarily by multiplying A by
exp(ift) for some f. Setting Plot type = 1 shows the magnitude of A, and Plot type = 2 shows the phase.
