I wanted a command to be executed when 'x_n' and 'y_n' meets a certain condition, but the nested 'if' statement does not seem to be working.

Any help would be appreciated.

(x and y are vectors and the 'for loop' is going through their values)

for n = 2:length(t)
     
   clf
   plot([target,(target+0.5)],[0,0],'b','Linewidth',3);
   hold on
   t_n = t(n); 
   x_n = x(n);
   y_n = y(n); 
   if y_n == 0.25 && x_n>=target && x_n<=(target+0.5) %condition of x_n and y_n where the ball is supposed to land
       ytest = y_n;
       xtest = x_n;
       break
       % intended for the projectile to stop as if it landed on the board
   end
   plot(x_n,y_n,'ro','LineWidth',4,'MarkerSize',5)
   ylim([-1,2.5])
   xlim([0,3])
   drawnow
   
end
