ODE 001 - Code


We have the ordinary differential equation:
y'' + 5y' + 6y = 0      y(0) = 2   y'(0) = 0

To the left you see the code for a Python program solving this differential equation numerically and drawing the graph.

The function odeint from the library scipy.integrate solve this differential equation.
odeint has three parameters:
model : function call where you have the mathematical model in the diff.eq.
y0    : initial value [y(0)=2, y'(0)=0]
t     : time array
The two first parameters (model and y0) are transferred to the first parameter y in the model function.
The body part (line 19-37) of model contains the mathematical model of the diff.eq.
