How I display inline function?

Dear all,

I have this inline function (('(x-j).^2+(y-0.5).^2<0.1^2','x','y','z'), where j is variable (j= 0:0.5:1). So my function for example looks like (('(x-0.5).^2+(y-0.5).^2<0.1^2','x','y','z'). And I want to this function display in my figure (image = img_2) so it displays this fleck.

But in my for loop, there is something wrong, because there are all flecks in one figure (image = img_2) so it displays this

Do you have any idea? I enclose my code.

Thank you very much for your answer.
