So I've been given this system of equations in Matrix form: X' = [5 -1 ; 3 1]X where the bracketed portion is the 2x2 matrix A. By default it will be colored in shades of a solid color, but it also supports color mapping by supplying the cmap argument. I even have a sketch of the trajectories (with the point (0,0) as an unstable node) all set up as well so I have an idea of what the actually plot will look like. This is the first post in a two part series on building a motion detection and tracking system for home surveillance. Many functions are derived from the perspfunction, other functions start from the imageor contourfunction. import numpy as np. Once we have the desired acceleration trajectory, we need to remove the effect of the base point attractor system. So basically you won't always be plotting graphs straight up from a Python IDLE by typing in that data. However, matplotlib is able to plot a generic, parametric 3D surface.
