For loop that moves through array of X, Y coordinates

I am trying to write a program that moves a picture around a screen at designated X,Y coordinates. I have assigned the X and Y vector locations and paired them in an array,

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;];
    Paired_Vectors = [X_vector, Y_vector];

but am having trouble telling Matlab to loop through the paired X,Y coordinates to assign the location of the picture to new locations after a specified amount of time.

What type of for loop should I run? Would it be better to run a for loop for X_vector and Y_vector indepedently? How would I still maintain the paired relationships?

Since you already have the x and y separately I don't see why you need to create a new, single matrix out of them. Just use the existing ones you already have.

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

The relationship is still "paired" because for any given index, the x value and y value correspond to each other.

Works perfectly! Thank you so much!
