cache1 = [
0.814723686393179 0
0.905791937075619 1
0.126986816293506 2
0.913375856139019 3
0.632359246225410 4];
chunk1 = [
1.21602018873774 10
-2.22909989155828 10
0.893185966969769 9
1.02908840545717 9
-0.849841587777029 8];
for i = 1: size(cache1,1)
if cache1(i,2) < 6
ind = 11 - cache1(i,2)
cache1(i,1) = max(chunk1(chunk1(:,2) == ind));
end
end
chunk1(:,2) is nowhere equal to 11, so the right-hand side is empty.

Hi,
In the code sample that you shared, chunk1(:,2) == ind returns a 5x1 logical array containing only zeros.
Since MATLAB uses 1-indexed arrays, chunk1(chunk1(:,2) == ind) returns a 0×1 empty double column vector, and hence you get the error.
This is happening because none of the values in the second column of chunk1 match the value of 11 - cache1(i,2).
