Algorithms will be presented for the Tanh and Sech methods that lead to closed-form solutions of nonlinear ordinary and partial differential equations (ODEs and PDEs). New ...

The finite element method is the standard approach for solving partial differential equations in geometries in which the boundaries are not simple variable ranges. This ...

Since Wolfram Language added TimeSeries and DateObject, there are more dated data than ever waiting to be visualized. Come to see what we have worked on since the last year ...

I wrote these high school notebooks in two different styles for teachers to use either directly or as examples of what they might want to imitate or avoid. One style has ...

This is a Mathematica notebook containing functions and graphics of interference and diffraction patterns. Pictured here is a surface of Fresnel Diffraction, described ...

The problem of the extraction of electron energy distributions from probe measurements in plasmas is based on the solution of ill-conditioned integral equations. The simple ...

Robotica is a Mathematica package for analysis of robot kinematics, dynamics, and control. It encapsulates over 30 functions for symbolic and numerical computation, ...

Counting of several families of relations is done under conjugacy equivalence by means of Burnside's lemma following the ideas of Davis. The families include relations in ...

In most Mathematica animations, one cell replaces another. Unfortunately this is not always a practical approach, and many users would like a way of creating an animation ...

A Mathematica package for the computation of stable distributions is demonstrated. Calculations of stable density, distribution, and quantile functions can be performed and ...
