Computes the upper envelope of a function.

This package provides a useful general utiltity function, Unshadow, which will clean up every symbol in the global context that interferes with a symbol in another context, ...

The Mathematica functions Positive, Negative, and NonNegative evaluate for numbers only. They can be used to define properties of symbols but for combinations of such ...

Complex algebraic numbers form a new class of "infinite precision" numbers available in Mathematica 3.0. Content: root isolation; ordering the roots; computation with ...

This book goes beyond a presentation of the basic functions of the software to describe the full range of its functionality. These functions range from simple calculations to ...

SouperPrediktor is a Mathematica package that searches function space for functional fits to arbitrary data using genetic algorithm techniques. The program provides a large ...

This package contains functions that will draw a Smith chart. A Smith chart is useful for plotting how the impedance of a circuit changes as a function of frequency or how ...

We describe the use of Mathematica in the investigation of some aspects of finite geometry, in particular we look at an example of finding a single polynomial function ...

The functions we present here implement the classical method of Lagrange multipliers for solving constrained optimization problems. The moat problem that we employ to ...

This book shows how to solve physical problems and deal with their underlying physical concepts while using Mathematica to derive numeric and symbolic solutions. The ...
