Managing Variables

Variables are either built as global variables or user-defined in the current workplace. For example, pi is built-in, and assinged the numeric value 3.1416..., but the user can override the built-in by locally defining

> pi = 3

To list locally defined variables, type

> whos

To delete the user-defined variable, type

> clear pi

Then it recovers the built-in value of pi.
