Many of the most powerful list manipulation operations in Mathematica treat whole lists as single objects. Sometimes, however, you need to pick out or set individual elements ...

Mathematica uses various syntactic rules to interpret input that you give, and to convert strings and boxes into expressions. The version of these rules that is used for ...

FindHamiltonianCycle[g] attempts to find a Hamiltonian cycle.

Converting between strings and lists of characters. This gives a list of the characters in the string. You can apply standard list manipulation operations to this list.

MathLink provides a mechanism through which programs can interact with Mathematica. Some typical uses of MathLink. MathLink provides a general interface for external programs ...

Mathematica supports state-of-the-art sound generation, providing both arbitrary waveform synthesis from functions and data, and symbolic note-based MIDI-style sound ...

PermutationCyclesQ[expr] returns True if expr is a permutation in disjoint cyclic form, and False otherwise.

True is the symbol for the Boolean value true.

Testing for numeric quantities. Pi is a symbol, so Pi+3 is not explicitly a number. It does however have a numerical value.

When you use //N to get a numerical result, Mathematica does what a standard calculator would do: it gives you a result to a fixed number of significant figures. You can also ...
