Finding corresponding interpolated x values for defined y values

Hi all,
I have obtained data and plotted it. I then interpolated it via spline interpolation and everything works fine. However, I would like to obtain precise values for the t2 (i.e. the interpolated x values) coordinates at say 10%, 20%, 30% etc., of the maximum y2 (i.e. interpolated y values) value.
The answer I obtain is
ans =
Empty matrix: 1-by-0
Please see the code below. I hope you can help.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
x = KE_data(:,1);
y = KE_data(:,2);
t2 = -20.5005:0.00002457:-20.2548;
y2=interp1(x,y,t2);
max_y2 = 0.1*max(y2);
t2((y2==max_y2))
