Use sort instead of min, and pick as many as you want:
>> [v,x] = sort(abs(k(:)-1));
>> [p,n,m] = ind2sub(size(k),x(1:3)) % closest three
p =
6
3
6
n =
9
4
8
m =
2
2
4
>> k(p(1),n(1),m(1)) % (first) closest.
ans = 0.99869
>> k(p(2),n(2),m(2)) % second closest.
ans = 0.99852
>> k(p(3),n(3),m(3)) % third closest.
ans = 0.99852
Use linear indexing to easily access the values in k, here are the closest ten values:
>> k(x(1:10))
ans =
0.99869
0.99852
0.99852
0.99852
0.99834
0.99816
0.99781
