With interface-based communication, there are common steps that comprise the basic workflow. You create an object of the interface type you are using, and connect to the instrument. Setting properties is optional, but common. You read and write data, and disconnect and clean up.

You need to create a MATLAB® object that represents the instrument to communicate with the instrument.
Before you can use the instrument object to write or read data, you must connect it to the instrument whose address or port is specified in the creation function.
You can configure the instrument object behavior by assigning values to properties.
You can write text or binary data to the instrument and read text or binary data from the instrument.
You can use SCPI commands with the Instrument Control Toolbox™ and the MATLAB programming environment to control multiple instruments using similar functions.
Disconnect the object from the instrument, and remove the object from memory and from the workspace.
