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

1 view (last 30 days)
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
