用英文写出上面一段代码的伪代码

Here is the pseudocode for the given MATLAB code:

function draw(ballposition, paddles, scores)
    set global variables WIDTH, HEIGHT, PADDLE_LENGTH, SCORE_LIMIT
    set PADDLE_WIDTH = 10
    plot the ball at position (ballposition(1), ballposition(2)) with size 20 and black color
    make the scale of the coordinate axis uniform
    remove scales while retaining borders
    limit the range of drawing from 0 to WIDTH for x-axis and 0 to HEIGHT for y-axis
    draw the table tennis net with a black dashed line from (WIDTH/2, 0.2*HEIGHT) to (WIDTH/2, 0.8*HEIGHT)
    display the round count as "Round (sum(scores) + 1)" at the center of the plot
    display the round limit as SCORE_LIMIT at the center of the plot, below the round count
    display the scores of player 1 and player 2 at (0.4*WIDTH, 0.8*HEIGHT) and (0.6*WIDTH, 0.8*HEIGHT) respectively
    draw the paddle of player 1 as a black rectangle with width PADDLE_WIDTH and length PADDLE_LENGTH, centered at (paddles(1, 1), paddles(1, 2))
    draw the paddle of player 2 as a black rectangle with width PADDLE_WIDTH and length PADDLE_LENGTH, centered at (paddles(2, 1), paddles(2, 2))
end function
