Create a matrix with random integers between 1 and 9

Hello.

I need help creating a 3x3 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!

     3     5     4
     7     1     9
