How can I generate a set containing all possible combinations?

Let say I want to have a 2x2 matrix and the entries are chosen from numbers 1-8 (without repetition).

How can I generate a set that contains all the possible matrices? Thanks a lot!

Answer 1

[KSSV]

Read about perms

[Thomas Lu]

I read it and I came up with perms(combnk(1:8,4)), but the program said it exceed the sizes limit...

[KSSV]

v = randsample(1:8,4) ; 
p = perms(v) ; 
A = reshape(p',2,2,[]) ; 

Answer 2

[Bruno Luong]

A = nchoosek(1:8,4);
A = num2cell(reshape(A',2,2,[]),[1 2]);
A = A(:);
% display
A{:}

Produces 70 2x2 matrices
