How to make variables in a while loop be an array

Could anybody help me with this please? I am trying to work out a optimisation problem. I am using a while loop. I am able to obtain results in an array e.g. result(n).however, I am not able to make variable "n" as an array,hence, the value that I can access is always the last n value appeared. I would like to know how to make the variables into an array form that I can access the optimal result,aslo the corresponding variable "n" value.

idx = 0;
while ....
n = ....
result(n) = ....
idx = idx + 1; %!
all_n(idx) = n; %!
end
Then later you can (for example)
for K = 1 : idx
this_n = all_n(idx);
disp(result(this_n))
end

[maxvalue, maxidx] = max(result);
Then the index of the maximum value is maxidx
This does not require that the n be recorded.
