How to create a random 3D matrix?

Question

Is there any way of creating a 3D matrix randomly? There are ways to create random 2D matrices using randint function. Is there any inbuilt function like that?

E.g.

Answer 1

If you read the help carefully, you will notice that the randi function accepts any number of dimensions. You may do randi(10,3,3,3)

randi(10,3,3,3)

ans(:,:,1) =

     9    10     3
    10     7     6
     2     1    10


ans(:,:,2) =

    10    10     2
     2     5     5
    10     9    10


ans(:,:,3) =

     8     1     7
    10     9     8
     7    10     8
