Algebra Triangles

This script implements the three standard relational join algorithms: nested loops join, hash join, and merge join, using the iterator algebra support in Python.This script also presents code that can be used for inner join, left outer join, full outer join, and semijoins. The nested loops join...

The script has many functions that deal with homogeneous transformations and Lie algebra.The toolbox also includes, a set of functions for interacting with serial link kinematic structures. There are functions for generating nice plots and animations of the results. Key features "Kinematics...

ECC library is a package for Elliptic Curve cryptography.ECC is implemented by using OpenSSL 0.9.6a or higher, for message digests and symmetric ciphers, and by using the Portable Object Compiler and Computer Algebra Kit for the elliptic curve cryptography.

This program demonstrates the quaternion belt-trick, also known as the Dirac belt-trick and the waiter trick. It generates an AVI movie file (also included) which shows a stereo movie of the belt-trick in action. Notes: (1) If you want to save time and see the end-result, just watch the included...

The Rotation About a Fixed Axis example computes the angular momentum of a rigid rectangular box attached to a rotating axle. The fixed axis is in the z-direction. Users can tilt the box relative to the axle and can change the box dimensions. The simulation shows that the angular momentum vector...
