[Matlab] Quit or Exit External Process with Matlab

Windows (32/64), this is Not for Mac or Unix/Linux based systems. If you are running such a system and you don’t know how a kill a process from there you are an utter idiot.

Matlab Side

Call this from anywhere in Matlab (given that the folder where the below script is saved is actually added in your path).

Perl Side

save this in a file called quitproc.pl .

use warnings;
use strict;
use Win32::OLE qw(in);
my($input) = $ARGV[0];
my $exitcode;
my $objWMI = Win32::OLE->GetObject('winmgmts://./root/cimv2');
my $procs = $objWMI->InstancesOf('Win32_Process');
my @hits;
foreach my $p (in $procs) {
#push @hits => [ $p->Name, $p->ProcessID ]
    if($p->Name eq $input){
        #Now we kill the process
        kill 9, $pidnow; #SIGQUIT (quit signal) = 9
        print "Quit process: ", $procnow, ' (', $pidnow ,")n";

    The post clearly explains what and how it should be done.
    Thank you very much for sharing the code.
