Dear all,

I am trying to create FOR loop, because I want to change values (vector R) of variables i and j in my function :

 *('(x-j).^2+(y-i).^2<0.1^2','x','y','z')* . And after that I want to save this data into vector Q.

I try to do something, but it doesn´t work...

This is my code:

R = [0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1];

Q = [1:12];

for j = 1:numel (R)

i = R(j);

    R(1,:)>=0 & R(1,:)<=2;
  if find(0<i & i<2) == 1
    Q = i
  else 
['x-' num2str(j) '.^2+ (y-' num2str(i) '.^2<0.1^2,'  'x,'  'y,'  'z'];
select_fcn = inline('(x-j).^2+(y-i).^2<0.1^2','x','y','z');
img_2.elem_data = 1 + elem_select(img_2.fwd_model, select_fcn);
output(j)= Q;
 end
end
