ROS and MatlabSimulink LIDAR

Hello,

I am getting acquainted with the operation of the ROS environment and I was very interested in the project called turtlebot3. It allows me to simulate a robot with a lidar sensor and visualizations of this process in RVIZ. I would now like to download information about the lidar readings in order to develop a robot positioning algorithm between the table legs in the matlab. Unfortunately, despite the fact that the message / scan contains 360 items, Matlab allows reading only 128 items, which limits the reading angle of lidar to 128 degrees.

How can you fix it? I attach the screenshots in links:
