Generate all combinations of the elements of x taken m at a time. All combinations of v, returned as a matrix of the same type as v. C has k columns and n!/((n – k)! Its just a permutation of 3 numbers with repeatation. Seems good to me,except the typo on first line (2^N-1 instead of 2^N²-1).Plus I'd point out that this approach doesn't force you to store all of these combinations in memory, as it gives a 1:1 correspondance between your matrices and 0:2^N²-1, meaning if you just need to get one of these matrices at random for example, you can just pick a number and then apply the equivalence – … https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#answer_306763, https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#answer_306746, https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#answer_372153, https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#comment_698055, https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#comment_698224, https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#comment_698228, https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#comment_698230, https://uk.mathworks.com/matlabcentral/answers/384426-all-possible-combinations-of-0-s-and-1-s#comment_698242.
