Riffle[{e_1, e_2, ...}, x] gives {e_1, x, e_2, x, ...}. Riffle[{e_1, e_2, ...}, {x_1, x_2, ...}] gives {e_1, x_1, e_2, x_2, ...}. Riffle[list, x, n] yields a list in which ...

Functions for combining lists. Join concatenates any number of lists together. Union combines lists, keeping only distinct elements.

Version 6.0 added a collection of carefully optimized functions to Mathematica's powerful arsenal of numerical handling capabilities.

Mathematica's unified symbolic document architecture makes it possible to have flowing text contain any kind of object—including math, graphics or dynamic elements.

Lists are central constructs in Mathematica that are used to represent collections, arrays, sets, and sequences of all kinds. Well over a thousand built-in functions ...

Functions for manipulating elements in explicit lists. This gives a list with x prepended. This inserts x so that it becomes element number 2.

Integrated into the core Mathematica language is industrial-strength string manipulation, not only with ordinary regular expressions, but also with Mathematica's own powerful ...

Lists are at the core of Mathematica 's symbolic language. These "How tos" give step-by-step instructions for common tasks related to creating and manipulating lists.

In Mathematica's unified symbolic framework, graphics are treated just like any other expression—to be displayed, arranged, annotated, or manipulated using any of ...

Insert[list, elem, n] inserts elem at position n in list. If n is negative, the position is counted from the end. Insert[expr, elem, {i, j, ...}] inserts elem at position {i, ...
