Install["name"] starts a MathLink-compatible external program and installs Mathematica definitions to call functions in it.

PasteButton[expr] represents a button that pastes expr whenever it is pressed. PasteButton[label, expr] displays with label on the button.

Now that we have introduced the basic features of patterns in Mathematica, we can use them to give a more or less complete example. We will show how you could define your own ...

Some basic matrix operations. Transposing a matrix interchanges the rows and columns in the matrix. If you transpose an m×n matrix, you get an n×m matrix as the result. ...

Mathematica stores preference settings and initialization data in two directories, $BaseDirectory and $UserBaseDirectory. Within each of these directories are several ...

Lists are widely used in Mathematica, and there are many ways to construct them. Some explicit ways to construct lists. This gives a table of the first five powers of 2.
