For example, If I have two numbers [-1 1] in a some random order in a vector of length 6, how can I compute all 64 combinations of these numbers such that a result is a matrix of 64x6 dimension?
To make my question more clear, result would look something like this:
A = [-1 1 -1 1 -1 1; 1 -1 1 1 -1 -1 1; -1 1 -1 -1 1 -1; 1 -1 -1 1 -1 -1; etc.]
with all 64 possible combinations. Since there are 64 combinations, a resulting matrix needs to have 64 rows and 6 columns since every row (vector) has 6 numbers.

Brute force would be
unique(perms(A))
Maybe there is a better solution.

If you have a fixed vector v made up of -1 and 1 and you want to get all combinations of the elements of this vector, you get 6! permutations where many of them will repeat.
If you want all possible vectors of length 6 made up of the numbers -1 and 1, you get 64 such vectors.
I think the last thing is what you want, and permn will do this for you.
