So i have 3 numbers from 1-3. How would i create a matrix of all the possible outcome without repeating the number in each matrix.

such as

[1,2,3]

[3,2,1]

[2,1,3,]

[3,1,2]

......etc

Then display how many different combination there was.

The example i provided there are 4 rows total.

CombS = perms(1 : 3)
How_many = size(CombS, 1)
