running a set of numbers through a program

I have a region growing code where the input for the code looks like this.

 I = im2double(imread('medtest.png'));
 x=198; y=359;
 J = regiongrowing(I,x,y,0.2); 
 figure, imshow(I+J);

I need to run it multiple times using a set of coordinates such as

x = [1,2,3]
y = [4,5,6]

If anyone has anysuggestions i would greatly appreciate it.

What does run it multiple times using a set of coordinates such as

x = [1,2,3] y = [4,5,6]

really mean, precisely? You mean three consecutive runs w/

[x y]=[1 4];

etc., or somehow are the vectors supposed to be the arguments?

If the former, why isn't just a simple loop enough?

 I = im2double(imread('medtest.png'));
 X = [1 2 3]; Y = [4 5 6];
 for K = 1 : length(X)
   x = X(K); y = Y(K);
   J = regiongrowing(I,x,y,0.2); 
   figure, imshow(I+J);
 end
