GPIB is a standardized interface that allows you to connect
and control multiple devices from various vendors. For many GPIB applications,
you can communicate with your instrument without detailed knowledge
of how GPIB works. Communication is established through a GPIB object, gpib,
which you create in the MATLAB® workspace. For information about
creating the gpib object, see Creating a GPIB Object.
You can write and read both binary and text data. For examples of both, see Writing and Reading Data.

The GPIB object establishes a connection to an instrument via its GPIB interface.
The GPIB address consists of the board index of the GPIB controller, and the primary address and (optionally) the secondary address of the instrument.
Rules for read and write operations with GPIB and examples of writing and reading both text and binary data.
Enhance your instrument control communication using events and callbacks.
Send the GET (Group Execute Trigger) GPIB command to the instrument. This command instructs all addressed Listeners to perform a specified action.
Execute a serial poll where the Controller asks (polls) each addressed Listener to send back a status byte that indicates whether it has asserted the SRQ line and needs servicing.
