Package Commands
To use a package command, the calling sequence must include the package
name, and the command name enclosed in brackets ([ ]).
package[command](arguments)
If you are frequently using the commands in a package, load the package.
To load a package:
• Use the with command, specifying the package as an argument.
The with command returns a list of the package commands loaded (unless
you suppress the output by entering a colon at the end of the calling se-
quence).
After loading a package, you can use its commands as top-level commands,
that is, without specifying the package name.
For example, use the NLPSolve command from the Optimization package
to find a local minimum of an expression and the value of the independent
variable at which the minimum occurs.
