This block receives a ROS message of type sensor_msgs::LaserScan. Each time the block is run by its time domain, the last message received is driven on its output signals.

  // define a handler for ROS nodes
  ros::NodeHandle rosNodeHandler;                                    
  // create subcriber block, laserscanner range has a size of 150 values
  RosSubscriberLaserScan<Matrix<150, 1, double>, Matrix<150, 1, double >> laserScan(rosNodeHandler, "myNode/myTopic", 100, false);

The template parameter of the block determines the size of the range and intensity vectors.
