Packages
- Many commands are built into Mathematica, but many more specialized ones
are defined in packages. Packages are files that contain definitions of Mathematica
functions. To use a package, you must load it into Mathematica. To load a package,
you need to know what directory it is in. For example, the package file
Colors.m
is inside the directory Graphics. To load Colors.m,
you must evaluate the following command.
<< Graphics`Colors`
- In Mathematica, you can use the notion of "contexts" to organize
the names of symbols. Contexts are particularly important in Mathematica
packages that introduce symbols whose names must not conflict with those of any
other symbols. The full name of any symbol is broken into two parts: a context
and a short name. The full name is written as context`name,
where the `
is the backquote or grave accent character, called a "context mark" in
Mathematica.
- To use one of the standard add-on packages, go to Standard
Packages in the Add-ons section in the
Mathematica Help Browser to find out about the hundreds of
additional functions supplied with every full copy of
Mathematica. Topics include graphics, numerics,
discrete math, data tables, and much more.
