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

That gives 8 combinations. How do I get 8^t combinations?

Thanks

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')
