MATLAB: Anyone can help me to understand this code

anyone can help me to understand this code?

a = arduino();
imu = mpu6050(a,'SampleRate',50,'SamplesPerRead',10,'ReadMode','Latest');
    figure;
    xlabel('Time (s)');
    ylabel('Acceleration (m/s^2)');
    title('Acceleration values from mpu6050');
    x_val = animatedline('Color','r');
    y_val = animatedline('Color','g');
    z_val = animatedline('Color','b');
    stop_time = 10; %  time in seconds
    count = 1;
    tic;
    while(toc < stop_time)
    data = read(imu);
    addpoints(x_val,count:(count+imu.SamplesPerRead-1),data.Acceleration(:,1));
    addpoints(y_val,count:(count+imu.SamplesPerRead-1),data.Acceleration(:,2));
    addpoints(z_val,count:(count+imu.SamplesPerRead-1),data.Acceleration(:,3));
       count = count + imu.SamplesPerRead;
       pause(0.001);
    end
    release(imu);

It configures an arduino. It configures an accelerometer attached to the arduino. It initializes some variables.
Then it loops for a set amount of clock time, reading 10 accelerometer samples at a time, each with 3 channels, X Y Z. It adds the received data to the corresponding graphics line. It pauses for one millisecond. In this context, really the pause is there to tell the graphics system it is okay to update the display.
