Palettes give you immediate access to many features built into Mathematica, from creating syntactically complete expressions and inserting special characters, to building up ...

Many calculations involve solving systems of linear equations. In many cases, you will find it convenient to write down the equations explicitly, and then solve them using ...

Directly integrated into Mathematica's uniform architecture for handling lists of data is an array of highly optimized algorithms for transforming and smoothing datasets that ...

Mathematica 7 extends its general treatment of lists and matrices by adding a variety of convenient functions, including support for common convolution and structure matrices.

Mathematica has powerful capabilities for explicit signal processing with large volumes of data, imported and exported in many formats, and for symbolic analysis of signal ...

Which[test_1, value_1, test_2, value_2, ...] evaluates each of the test_i in turn, returning the value of the value_i corresponding to the first one that yields True.

$TimedOut is a special symbol returned by certain functions when an operation times out.

An important feature of string manipulation functions like StringReplace is that they handle not only literal strings but also patterns for collections of strings. This ...

ScriptLevel is an option for selections that is used in determining the font size of modifiers such as subscripts and superscripts in a nested expression.

Scan[f, expr] evaluates f applied to each element of expr in turn. Scan[f, expr, levelspec] applies f to parts of expr specified by levelspec.
