The multivariate normal distribution is easy to implement in Mathematica. This article presents self-contained code which allows one to specify any multidimensional normal ...

Recently Pawlowski and Raczka (P&R) proposed a unified model for the fundamental interactions which does not contain a physical Higgs field. The gravitational field equation ...

The discrete cosine transform (DCT) is a technique for converting a signal into elementary frequency components. It is widely used in image compression. Here we develop some ...

Polar symmetry plots are a useful way to visualize time series or digitized wave forms. These plots are easily produced with Mathematica. The examples presented here ...

Nonlinear mappings of the complex plane that possess dihedral or cyclical symmetry are a natural symmetrical generalization of the logistic map. We explore the properties of ...

A three-dimensional anisotropic super micro-etching of crystalline silicon in aqueous KOH is simulated on an atomic level using a new three-dimensional cellular-automata ...

A compendium of mathematical definitions, formulas, figures, tabulations, and references. Provides a highly readable, distinctive text applicable to a broad spectrum of ...

A model of a luge run is constructed. A slider races down the luge run at sixty miles an hour. A camera capable of generating the illusion of passing through a scene is ...

This fully documented package adds the functionality of a TriangleDistribution to the continous distributions of the standard statistics package. The entire collection of ...

Used by mathematics educators, researchers, and graphical designers, Geometrica is a Mathematica application for exact drawing and geometry. With it, you can draw points, ...
