ColorQuantize[image, n] gives an approximation to image that uses only n distinct colors.

As with integers, operations related to division are key to many computations with polynomials. Mathematica includes not only highly optimized univariate polynomial-division ...

Fold[f, x, list] gives the last element of FoldList[f, x, list].

Mathematica supports hyperbolic functions everywhere in the complex plane—with careful attention to branch cuts—and provides an extensive web of exact and algebraic ...

Polynomial algorithms are at the core of classical "computer algebra". Incorporating methods that span from antiquity to the latest cutting-edge research at Wolfram Research, ...

Mathematica gives you the ability to fine-tune the level of detail for your plots. To get a rough sketch of a plot, you can tell Mathematica to plot fewer points. The more ...

ImageCrop[image] crops image by removing borders of uniform color. ImageCrop[image, {w, h}] crops image to pixel width w and pixel height h.ImageCrop[image, size] crops image ...

Mathematica's extensive base of state-of-the-art algorithms, efficient handling of very long integers, and powerful built-in language make it uniquely suited to both research ...

Packing a large number of sophisticated algorithms—many recent and original—into a powerful collection of functions, Mathematica draws on almost every major result in number ...

The representation of algebraic numbers. When you enter a Root object, the polynomial that appears in it is automatically reduced to a minimal form. This extracts the pure ...
