Andrew D. Lewis's Mathematica programs

[Documentation List] [Decoding instructions]

  1. Affine: Some affine differential geometry functions.
  2. Constraints: There are some functions here to do things for constrained mechanical systems in the affine connection framework.
  3. Coordinates: There are a (very) few functions for doing coordinate changes for tensors.
  4. InnerProduct: Some basic operations for inner products spaces.
  5. SimpleSystems: Simple mechanical systems with symmetry.
