ZernikeR[n, m, r] gives the radial Zernike polynomial R_n^m(r).

Palettes give you immediate access to many features built into Mathematica, from creating syntactically complete expressions and inserting special characters, to building up ...

Directly integrated into Mathematica's uniform architecture for handling lists of data is an array of highly optimized algorithms for transforming and smoothing datasets that ...

Mathematica 7 extends its general treatment of lists and matrices by adding a variety of convenient functions, including support for common convolution and structure matrices.

The method "DoubleStep" performs a single application of Richardson's extrapolation for any one-step integration method. Although it is not always optimal, it is a general ...

Mathematica has powerful capabilities for explicit signal processing with large volumes of data, imported and exported in many formats, and for symbolic analysis of signal ...

The Mathematica function NDSolve is a general numerical differential equation solver. It can handle a wide range of ordinary differential equations (ODEs) as well as some ...

Definitions such as f[x_]=x^2 specify values for functions. Sometimes, however, you need to specify general properties of functions, without necessarily giving explicit ...

Which[test_1, value_1, test_2, value_2, ...] evaluates each of the test_i in turn, returning the value of the value_i corresponding to the first one that yields True.

Reals represents the domain of real numbers, as in x \[Element] Reals.
