Random generator with constraints

I am getting back into MATLAB and need to create a random generator that provides a matrix of 12 rows by 4 colums of numbers from (1,4), with non repeating numbers in row. And another separate random generator code that can provide a 1 row by 5 colums of numbers for (0,4), with non repeating numbers in row.

sz = [12,4]; 
maxVal = 4; 
M = cell2mat(arrayfun(@(i){randperm(maxVal,sz(2))},1:sz(1))');

>And another separate random generator code that can provide a 1 row by 5 colums of numbers for (0,4), with non repeating numbers in row.

V = randperm(5,5).'-1;

Steven Lord's approach is simpler for the first part of the question.

Answer 2

[Steven Lord]

A = rand(6, 4);
[~, ind] = sort(A, 2)

ind = 6×4

4 1 2 3 4 2 3 1 1 2 3 4 4 2 1 3 2 4 3 1 1 3 2 4
