KaleidoTile vs Polynomial Regression

Explore polyhedra and tilings while creating colorful kinematic art. Polyhedron mode lets you create traditional polyhedra, while Tiling mode smooths your polyhedra into tilings of the sphere, Euclidean plane or hyperbolic plane. Decorate your work with images from your photo library, fresh images from the camera, or colors. Within each symmetry group, any polyhedron or tiling morphs to any other; for example, you may morph a dodecahedron to an icosahedron, confirming that they share the same symmetries. KaleidoTile comes with a guide to Tilings and Symmetry.

Polynomial Regression is your calculator and, more importantly, learning tool. You will be able to: * Construct polynomials of up to 20 degrees from either real or complex roots. * Interpolate polynomials from points by Lagrange, Newton or Vandermonde methods and Quadratic or Cubic splines. * Perform Least Squares approximation by orthogonal projection, with or without QR factorization, or partial derivatives. * Learn about each of the algorithms with derivations, proofs, step by step demonstrations, and visual tools. * Have an option to enter data by either typing or tapping on XY plane, and save data sets between program runs.
