animate multiple lines one by one

Hello! I'm just getting started with matlab. Now I have some questions with animation creation. I have an array U1, size 101*101. I need to make an animation from the line graphs of each 20th column of this array. They need to come out one by one. I made an example of how it should look like, but I can't implement it. So far, I was only able to display the graphs of each line in one figure. plot(x, U1(:,1:20:end)) Please tell me how to create this animation or can you advise the literature where there are similar examples. Thank you!

You could do something like this

% Make some example data
U1 = rand(101,101)
x = linspace(1,10,101);

% plot every 20th column of the data in a loop so it appears animated
tPause = 1; % pause time in seconds between displaying each curve
n = 20; % curve increments
numCol = size(U1,2); % number of columns in data matrix
numCurves = floor(numCol/n); % number of curves to be plotted
for k = 1:numCurves
    plot(x,U1(:,k))
    pause(tPause)
end
