How to create a for loop

Dear all,

This is a part of my code:

('x-'num2str(i)').^2+(y-'num2str(j)').^2<0.1^2','x','y','z');

select_fcn = inline('(x-i).^2+(y-j).^2<0.1^2','x','y','z');

I want to create a for loop to change variables i and j. For example i=0.5 and j=0.1, not the same values like i=0.5 and j=0.5.

Thank you for your answers.
