$MinNumber gives the minimum positive arbitrary-precision number that can be represented on a particular computer system.

$NewSymbol is a global variable which, if set, is applied to the name and context of each new symbol that Mathematica creates.

Modules in Mathematica allow you to treat the names of variables as local. Sometimes, however, you want the names to be global, but values to be local. You can do this in ...

Monte Carlo methods use randomly generated numbers or events to simulate random processes and estimate complicated results. For example, they are used to model financial ...

The method "DoubleStep" performs a single application of Richardson's extrapolation for any one-step integration method. Although it is not always optimal, it is a general ...

The precise details of the naming of files differ from one computer system to another. Nevertheless, Mathematica provides some fairly general mechanisms that work on all ...

Mathematica's symbolic architecture allows a unique representation and treatment of images in both programs and documents. Mathematica supports images with arbitrary numbers ...

Version 8.0 introduces new features to load functions from shared libraries, giving a new way to incorporate external code into Mathematica. It also adds support for GPU ...

There will be times when you want to stop Mathematica in the middle of a computation. You may have asked Mathematica to do something that you did not intend or that is taking ...

ChanVeseBinarize[image] finds a two-level segmentation of image by computing optimal contours around regions of consistent intensity in image.ChanVeseBinarize[image, marker] ...
