"Defining Functions" discusses how you can define functions in Mathematica. In a typical case, you would type in f[x_]=x^2 to define a function f. (Actually, the definitions ...

Combining a new level of programmatic support for symbolic color with carefully chosen aesthetic color parametrizations, Mathematica allows a uniquely flexible and compelling ...

$KernelCount gives the number of subkernels available for parallel computations.

Mathematica can import common terrain elevation files and render them as topographic maps. It can also import geospatial information formats that combine layers of raster, ...

Kernels[] gives the list of running kernels available for parallel computing.

Compile[{x_1, x_2, ...}, expr] creates a compiled function that evaluates expr assuming numerical values of the x_i. Compile[{{x_1, t_1}, ...}, expr] assumes that x_i is of a ...

Mathematica's symbolic representation of both graphics and controls makes it particularly easy to create click-interactive panels in which the user clicks or drags elements ...

Mathematica's unified symbolic graphics architecture makes possible powerful mixing of programmatic graphics generation with interactive editing and control. The Mathematica ...

Basic two-dimensional graphics elements. Here is a line primitive. This shows the line as a two-dimensional graphics object.

Mathematica includes a wide selection of carefully chosen color schemes that can immediately be used throughout the Mathematica graphics and visualization system.
