[mathcad] RE: Lorentz equation - simulation

Author: Oakley, Philip UK Posted: Thu, 28 Oct 2004 10:57:52 +0100

Hi
I'm doing a maths course on Dynamical Systems. Most of the folk use Matlab (all those toolboxe$).
I'd like to be able to do the same simulations in Mathcad but am lost when they showed the Lorentz non-linear differential equation simulation:

Lorentz equations
x' = s(y-x)
y' = r.x-y-x.z
z' = x.y-b.z
s,r,b are parameters.

An example plot is attached.

How would I achieve something similar in mathcad?

Dear Philip at http://www.csuohio.edu/physics/kaufman/mcad.html I posted
several mathcad files for physics courses including one on the Lorenz
attractor used in the Environmental Physics course.

Product Reviews

"Our work ranges from complex medical imaging research to large-scale mapping and diagrams and we need a tool that is able to handle anything we investigate. With Mathcad, we are able to manipulate and analyse our data quickly while at the same time documenting our work, for sharing and publication. We also use it for pilot studies conducted in support of research grant applications. It is an end-to-end tool for research and development."
Dr. Kenneth Castleman, President of Advanced Digital Imaging Research (ADIR), Houston, Texas

"Mathcad is an integral product for my work... With Mathcad, itís easy to disseminate design calculations because the documents look like real math. Thereís very little I canít do in Mathcad. The main benefits come from the format, which resemble a typed set of calculations. These programs are easier to develop by engineers and easier for others to follow and review since the logic is expressed in a familiar manner. The format is what places Mathcad head and shoulders above other programs of a similar function."
Andre Pavlov, Structural Engineer, Florida Department of Transportation
