Instrument Control Toolbox    
clear

Remove instrument objects from the MATLAB workspace

Syntax

Arguments

obj
An instrument object or an array of instrument objects.

Description

clear obj removes obj from the MATLAB workspace.

Remarks

If obj is connected to the instrument and it is cleared from the workspace, then obj remains connected to the instrument. You can restore obj to the workspace with the instrfind function. An object connected to the instrument has a Status property value of open.

To disconnect obj from the instrument, use the fclose function. To remove obj from memory, use the delete function. You should remove invalid instrument objects from the workspace with clear.

Example

This example creates the GPIB object g, copies g to a new variable gcopy, and clears g from the MATLAB workspace. g is then restored to the workspace with instrfind and is shown to be identical to gcopy.
