Did you try a nested for loop? It's very simple/basic. A brute force method but should be very fast especially for arrays this small. Come on, give it a try. I know you can do it if you just make an attempt because a for loop is about the very first thing you learn in programming. Here, I'll get you started...
for hk = 1 : length(H)
hValue = H(hk)
for hs = 1 : size(All_St1, 2)
value1 = All_St1(1, hs);
value2 = All_St2(1, hs);
value3 = All_St3(1, hs);
if ........
end
end
See if you can finish it.
