Building on its broad strengths in mathematics in general, and in special functions in particular, Mathematica provides a unique level of support for multiplicative number ...

In Mathematica's standard notebook interface, you are directly giving input and getting output every time you press Shift+Enter. Although much more rarely needed than in more ...

Ways to get pieces of matrices. Matrices in Mathematica are represented as lists of lists. You can use all the standard Mathematica list-manipulation operations on matrices. ...

N[expr] gives the numerical value of expr. N[expr, n] attempts to give a result with n-digit precision.

With its core symbolic paradigm and immediate access to sophisticated numerical, symbolic and geometric algorithms, Mathematica is able to provide a uniquely flexible and ...

Finding the structure of polynomials written in expanded form. Here is a polynomial in two variables. This is the polynomial in expanded form.

FindDivisions[{x_min, x_max}, n] finds a list of about n "nice" numbers that divide the interval around x_min to x_max into equally spaced parts. FindDivisions[{x_min, x_max, ...

Setting[expr] replaces control objects such as sliders or popup menus in expr by their settings.

Mathematica by default interprets any sequence of letters or letter-like forms as the name of a symbol. All these are treated by Mathematica as symbols. Symbols with built-in ...

The introduction of Mathematica 6 in 2007 represented a revolutionary redefinition of Mathematica. Arriving only 18 months after Mathematica 6, Mathematica 7 represents ...
