Create an array of all possible combinations?

I have a sensor. The sensor can have one of two possible readings ( Smax or Smin), one of two possible azimuths ( Amax or Amin), and one of two possible elevations ( Emax or Emin). Therefore I have 8 unique combinations.
Suppose I have ( t) total number of sensors. Now I have 8^ t number of unique combinations. I arrange the potential values of each variable into the following matrices:
- Smax=[tx1]
- Smin=[tx1]
- Amax=[1xt]
- Amin=[1xt]
- Emax=[1xt]
- Emin=[1xt]
I created a function f with the input variables S, A, and E. It can return 8^ t number of unique outputs. How do I write a script that will create an array of all the possible unique outputs?

One option:
x = nchoosek([1:2 1:2 1:2],3);
perm = unique(x, 'rows')
perm =
1 1 1
1 1 2
1 2 1
1 2 2
2 1 1
2 1 2
2 2 1
2 2 2

For a positive integer ‘t’ and two possibilities for each, this would work:
t = 5;
x = nchoosek(repmat([1 2],1,5),t);
perm = unique(x, 'rows')
