MATLAB: Finding the indexes of multiple elements that are equal to a certain value in an array

arrayshelphomeworkindexingMATLAB

W=400;Lb=5;Lc=3;
% a)
D = (1:0.01:2.9);
T = Lb*Lc*W./(D.*sqrt(Lc^2-D.^2));
[t,d]=min(T);
Specifically, I need help finding the D values where T increases 10 percent above its minimum value. My initial approach was to try and find the indexes of the elements in D that are equal to 1466.67, which is 10 percent above the function's minimum value, then plug them into D to find out what values those indexes correspond to. I've searching on here, and have tried using the find() command and the ismembertol() command, to no avail. I am probably using them wrong anyways, and would greatly appreciate any help in solving my problem.

 D(find(T>=t*1.1,1))
