export -- package item: export functions

Synopsis

Usage:
export {symbol1,symbol2,...}
Inputs:
- {symbol1,symbol2,...}, a list of symbols
Consequences:
- The symbols in the list, which should refer to functions or other symbols defined in the package, are made available to the user of the package, and are marked non-mutable.

Description

A package can contain the code for many functions, only some of which should be made visible to the user. The function export allows one to specify which symbols are to be made visible. For an example see an example of a package.

Use exportMutable to export symbols whose values the user is permitted to modify.
