MathieuCharacteristicA[r, q] gives the characteristic value a_r for even Mathieu functions with characteristic exponent r and parameter q.

A foundational idea in Mathematica is that all expressions—whatever they may represent—ultimately have a uniform tree-like structure.

LatticeData[lattice, " property"] gives the specified property for a lattice.LatticeData[n] gives a list of named lattices of dimension n.

Mathematica's symbolic character allows a powerful unification of the notion of conditionals in programming and in mathematics.

MathieuCharacteristicB[r, q] gives the characteristic value b_r for odd Mathieu functions with characteristic exponent r and parameter q.

Mathematica supports a variety of coordinate systems, organized for ease and efficiency of both direct and programmatic use. It supports convenient robust automatic range and ...

When building an initial statistical model, you may not have a good idea of what parametric distribution family it should come from. Nonparametric distributions make very few ...

BesselK[n, z] gives the modified Bessel function of the second kind K_n (z).

In many cases, you will find it convenient to communicate with external programs at a high level, and to exchange structured data with them. On almost all computer systems, ...

You can think of an expression like f[x] as being formed by applying an operator f to the expression x. You can think of an expression like f[g[x]] as the result of composing ...
