Matlab & ROS Co-simulation

I was referring to this one (https://www.mathworks.com/help/nav/ug/localize-turtlebot-using-monte-carlo-localization.html). Previously the matlab script test.m (localizaiton.m) gets stuck in the line:

waitForTransform(tftree,'/base_link','/base_scan', 5);

Now it works as below: image It is because rosinit initializes the ROS_IP incorrectly with some other unrelated IPs? Maybe it is because I picked wrong Matlab host IP from the so many ifconfig... image

image image Just tested, as long as the ip can be ping in the gazebo virtual machine, it works to be set as $ROS_IP at matlab side, but the gazebo side $ROS_IP has to be its own 192.168.235.128 and used in the localizaiton.m script. image image
