Remove a serial port object from the MATLAB workspace
Syntax
Arguments
obj |
A serial port object or an array of serial port objects. |
Description
clear obj
removes obj
from the MATLAB workspace.
Remarks
If obj
is connected to the device and it is cleared from the workspace, then obj
remains connected to the device. You can restore obj
to the workspace with the instrfind
function. A serial port object connected to the device has a Status
property value of open
.
To disconnect obj
from the device, use the fclose
function. To remove obj
from memory, use the delete
function. You should remove invalid serial port objects from the workspace with clear
.
Example
This example creates the serial port object s
, copies s
to a new variable scopy
, and clears s
from the MATLAB workspace. s
is then restored to the workspace with instrfind
and is shown to be identical to scopy
.
