idx=find(x==y)
And from the index, you get the value.

This will only turn up values that are exactly equal. Considering that float rounding errors are likely, this could miss several intersections.

tol=2*eps;
L_intersect = abs(y-y_line.Value) < tol;
x(L_intersect)
%you could use find(L_intersect), but you don't really need it here
