FeedbackType is an option for some control system functions that specifies the feedback type.

I represents the imaginary unit Sqrt[-1].

Version 7.0 introduces built-in zero-configuration parallel computing. Taking full advantage of Mathematica's unique symbolic architecture, Version 7.0 provides an ...

Tightly integrated into Mathematica's core language is a rich set of primitives for interacting with external environments. Mathematica's symbolic architecture makes possible ...

Mathematica is to its core a fundamentally extensible system, in which efficient, modular, reusable packages of any size can readily be created. Mathematica's symbolic ...

Implies[p, q] represents the logical implication p \[DoubleRightArrow] q.

NestWhile[f, expr, test] starts with expr, then repeatedly applies f until applying test to the result no longer yields True. NestWhile[f, expr, test, m] supplies the most ...

Even with "Newton methods" where the local model is based on the actual Hessian, unless you are close to a root or minimum, the model step may not bring you any closer to the ...

Abs[z] gives the absolute value of the real or complex number z.

Mathematica allows you to use special notation for many common operators. For example, although internally Mathematica represents a sum of two terms as Plus[x,y], you can ...
