if (loop==false && centre(ii,1)<95 )
centre(ii,:) = centre(ii,:)+ [0.1 0];
elseif (loop==false && centre(ii,2)<95)
centre(ii,:) = centre(ii,:)+ [0 0.1];
elseif (loop==false && centre(ii,1)>5)
centre(ii,:) = centre(ii,:)- [0.1 0];
elseif (loop==false && centre(ii,2)>5)
centre(ii,:) = centre(ii,:)- [0 0.1];
else
break
end
Lets's say centre(ii,1)=94.95, then the first if increases it to 95.05.
As soon as centre(ii,1)=95.05, the third condition makes it again 94.95 and the process continues. I want, once the first condition is achieved i.e. x>95, it should go to third condition. The similar case is for 2nd and 4th condition. How to do this?

@Walter Roberson, thank you for your kind support.
Let's say
these are two non interscting ploygons (shown below). How can i get a logical relationship out of this. Something like, if the polygons intersect or touch
paramter = true;
otherwise
parameter = false;
x1 =[-2.6967 -2.0891 -0.0846 1.5544 2.6872 -2.6967];
x2 = [5.6494 6.6386 6.6898 4.0313 1.3002 1.9802 5.6494];
y1 = [ 0.1340 -1.7104 -2.6987 -2.2076 -0.2624 0.1340];
y2 = [1.8624 3.4274 4.2346 6.6998 3.9686 2.2082 1.8624];
plot(x1,y1,x2,y2);
grid on;
poly1 = polyshape(x1',y1');
poly2 = polyshape(x2',y2');
polyout = intersect(poly1,poly2);
