generate a table of random number in specific range

Hi, i would like to generate a table with specific number of index range.

For example if k =3, the table [3x3] in specific number of range between 1 ,2 and 3 :

1 2 3

2 1 2

3 3 1

I'd use randi with the following syntax

X = randi(imax,n)

k=3;
X = randi(k,k)

X = 3×3

1 2 2 3 2 1 3 1 2

Did you look up rand() in the help? You would have learned how to do things like this:

% Define parameters.
minValue = 1;
maxValue = 3;
rows = 3;
% Create matrices:
m = minValue + (maxValue - minValue) * rand(rows)
% Or with integers:
m2 = randi([minValue, maxValue], rows, rows)
% Or with integers and no repeats:
m3 = reshape(randperm(rows^2), rows, [])

You'll see

m =

1.86651555049844 1.13391009681515 1.53934952237305

1.56954330912193 2.22280802997294 2.14026117843922

2.73713895445458 1.68866727412449 1.26436419354187

m2 =

1 1 3

3 1 2

2 3 1

m3 =

5 9 4

6 2 1

3 7 8
