user56621: I installed Octave support package for Arduino and it is listed in the packages installed when pkg list command is run.But when the command  "a= arduino('COM8')";
is run,"error: serial: Error opening the interface: No such file or directory" is shown.Please respond.

user69547: Using clear command on Octave before executing a=arduino('COM8') will remove this problem.
Use it like this:
clear
a=arduino('COM8')
