I understand that you want to simulate a simple triangle formation where three mobile robots move to the target coordinates [3,3; 4.5,6; 6,3] using the "Mobile Robotics Simulation Toolbox" in Simulink.
To accomplish this, refer to the following page - https://www.mathworks.com/matlabcentral/fileexchange/66586-mobile-robotics-simulation-toolbox and navigate to "Examples > Getting Started > Simulink Examples", then look for the example titled “Waypoint following using the Pure Pursuit Algorithm (Differential Drive)”. This Simulink model shows how to set up a multi‑robot simulation environment, assign each robot its own waypoint, and use Pure Pursuit Controller blocks to drive them toward their targets. You can adapt this example by replacing the default waypoints with your triangle coordinates to see the robots form the shape you want.
