How do i get both values of x for y=3.5

x=0:0.001:3.5;
y=5*sin(x);
figure
plot(x,y);
grid ON

target =3.5
[difference, index_At_target] = min(abs(y-target));
xtarget = x(index_At_target)

The result is showing only one output as xtarget=2.3660, where as there are two values of x for same y value. I want to obtain the other value from plot not by solving for y.

Result
xtarget =

      2.3660

 [sorted_difference, sort_index] = sort(abs(y-target));
 xtarget = sort(x(sort_index(1:2)));
