MATLAB: Create a matrix with random integers between 1 and 9

Question

Hello.

I need help creating a 3×3 matrix.

I need to create a matrix of integers between 1 and 9 allocated randomly each time and without repeating the same number.

Here's an example:

matrix =
     9     7     3
     5     1     8
     4     2     6
     

Thanks!

Answer 1

>> reshape(randperm(9),3,3)
ans =
     6     8     2
     3     5     4
     7     1     9
