The Interpretation of Textual Forms (Mathematica Tutorial)

Converting from strings or boxes to expressions. This takes a string and interprets it as an expression. Here is the box structure corresponding to the textual form of an ...

Parts of Expressions (Mathematica Tutorial)

Since lists are just a particular kind of expression, it will come as no surprise that you can refer to parts of any expression much as you refer to parts of a list. This ...

Dispatch (Built-in Mathematica Symbol)

Dispatch[{lhs_1 -> rhs_1, lhs_2 -> rhs_2, ...}] generates an optimized dispatch table representation of a list of rules. The object produced by Dispatch can be used to give ...

Naming Pieces of Patterns (Mathematica Tutorial)

Particularly when you use transformation rules, you often need to name pieces of patterns. An object like x_ stands for any expression, but gives the expression the name x. ...

The Syntax of the Mathematica Language (Mathematica Tutorial)

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 ...

Display of Numbers (Mathematica Guide)

Mathematica provides flexible mechanisms for full typeset formatting of numbers of any magnitude and precision, to optimize readability, portability, and external ...
