2delete (serial)
Purpose Remove a serial port object from memory
Syntax delete(obj)
Arguments
obj A serial port object or an array of serial port objects.
Description delete(obj) removes obj from memory.
delete (serial)
Remarks When you delete obj, it becomes an invalid object. Since you cannot connect an
invalid serial port object to the device, you should remove it from the workspace
with the clear command. If multiple references to obj exist in the workspace,
then deleting one reference invalidates the remaining references.
If you attempt to delete obj while it is connected to the device, then an error is
returned. A connected serial port object has a Status property value of open.
You can disconnect obj from the device with the fclose function.
If you use the help command to display help for delete, then you need to
supply the pathname shown below.
help serial/delete
Example This example creates the serial port object s, connects s to the device, writes
and reads text data, disconnects s from the device, removes s from memory
using delete, and then removes s from the workspace using clear.
s = serial('COM1');
fopen(s)
fprintf(s,'*IDN?')
idn = fscanf(s);
fclose(s)
delete(s)
clear s
