At least the value on Obs5(1,2) is <0.5
Obs5 = [0.5 0.4];
Z=rand(2,3);
old_obs_1 = plot3(Obs5(1,1), Obs5(1,2), Z(round(Obs5(1,2)),round(Obs5(1,1))),'o','MarkerSize',20, 'MarkerFaceColor','r','MarkerEdgeColor', 'k');

This error is simple, you are trying to extract more number of elements than present in the array.
A = rand ; % A is aconstat i.e 1x1 array.
A(1) % no error
A(1,2) % error becasue there is no second element, alse A(2) means the same
Check your variable dimensions. You have used index 2, it seemsthere is no second element.
