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 ...

We have developed an algorithm to compute the Hilbert-space basis and the operator algebra of descendant field for (1+1)-dimensional conformal field theories. Implemented as ...

A few transformations are presented for reducing certain cases of Meijer's G-function to a G-function of lower order. Their applications to the integration of a product of ...

This is a report on the Samuelson-Berkowitz-Abdeljaoued Algorithm (SBA), which is a very efficient computation of the characteristic polynomial in an arbtrary ring. We ...

The Chasing package provides a tool for numerical solution of linear multipoint boundary value problems. It has syntax of the built-in Mathematica function NDSolve and ...

In many cases plotting can be made easier by creating your own plotting functions which make use of the built-in functions of Mathematica. In such cases conflicts can occur ...

Replot is interactive and efficient companion of function Plot. It provides presets for the commonly used option values as well as direct keyboard input. It also conserves a ...

The forthcoming version of Mathematica will roll out the most radical overhaul of graphics since the program’s inception. This talk will cover the foundations of the new ...

We describe a package of Mathematica programs, originally devised for summer schools on aperiodic order and quasicrystals, which give an introduction to the construction of ...
