I have the following loop set up:
X_vector = [3; -3; -9; -15; -21; -15; -9; -3; 3; 3; -3; -9; -15; -21; -21; -15; -9; -3; 3; 3; -3; -9; -15; -21; -15; -9; -3; 3;];
Y_vector = [15; 15; 15; 15; 9; 9; 9; 9; 9; 3; 3; 3; 3; 3; -3; -3; -3; -3; -3; -9; -9; -9; -9; -9; -15; -15; -15; -15;];
for k = 1 : numel(X_vector)
x = X_vector(k);
y = Y_vector(k);
% Now use x and y in some way.
end
I want the loop to run through all the X and Y vector locations but change every 5 trials to the next X_vector and Y_vector pair (e.g. from (3, 15) to (-3, 15). Do I use a continue function to this?
Thank you in advance for your help!

Maybe this:
for k = 1 : numel(X_vector)
for n = 1 : 5
x = X_vector(k);
y = Y_vector(k);
% Now use x and y in some way.
end
end

Still not shifting unfortunately.

I interpreted the question to mean that you want to use the first element of X_vector and Y_vector 5 times, then go to the second element and use those 5 times, and so on, so that x and y would go like:
(3,15)
(3,15)
(3,15)
(3,15)
(3,15)
(-3,15)
(-3,15)
(-3,15)
(-3,15)
(-3,15)
(-9,15)
(-9,15)
(-9,15)
(-9,15)
(-9,15)
(-15,15)
(-15,15)
(-15,15)
(-15,15)
(-15,15)
etc.
If that's not what you want, then please explain what you do want.

Yep! Exactly what i want! When I tried your suggestion, it only ran 5 trials at the first paired X,Y coordinates then stopped.

Here's the same code as in my answer but with a disp statement to show (x,y) each time. You can see it's as intended.
X_vector = [3; -3; -9; -15; -21; -15; -9; -3; 3; 3; -3; -9; -15; -21; -21; -15; -9; -3; 3; 3; -3; -9; -15; -21; -15; -9; -3; 3;];
Y_vector = [15; 15; 15; 15; 9; 9; 9; 9; 9; 3; 3; 3; 3; 3; -3; -3; -3; -3; -3; -9; -9; -9; -9; -9; -15; -15; -15; -15;];
for k = 1 : numel(X_vector)
for n = 1 : 5
x = X_vector(k);
y = Y_vector(k);
disp([x,y]);
% Now use x and y in some way.
end
end

Maybe something in the code you're running (which is replaced by "% Now use x and y in some way." here) runs into an error, which causes execution to stop, or exits the loops early.

The error was on my end!! Thank you so much for helping me!! Your suggestion works like a charm!
