What is the syntax for iterating over given coordinates, using a For loop?

I have the following code:

X1= [10 12 14 23 24 23 18 16 12 10];
Y1= [20 20 18 15 8 7 8 6 12 20];

for i= X1 and j=Y1
    %code
end

I need the correct synatx where the For loop is initiated so that both arrays can be used for iteration simutaneously. I will appreciate any advice. Many thanks.

You can do this in the following way:

X1 = [10 12 14 23 24 23 18 16 12 10];
Y1 = [20 20 18 15 8 7 8 6 12 20];

for i = 1:numel(X1)
    xi = X1(i);
    
    for j = 1:numel(Y1)
        yj = Y1(j);
        
        % code using xi and yj
    end
end
