Creating an array without mesgrid

I am trying to create an array that looks like this (as an example)

X =

    | 1 2 3 |
    | 1 2 3 |
    | 1 2 3 |

Y =

    | 1 1 1 |
    | 2 2 2 |
    | 3 3 3 |

I tried doing a nested for loop inside a while loop, with this method, the Y array works but not the X array, I sort of understand why its not working but I dont know how to fix it.

this is what I got

X = []; Y = []; c=1;

while c<=3;

    for i=1:3

        for j=1:3
            X(i,c)=j;
            Y(i,c)=i;
        end
    end
    c=c+1;
end

I understand that the meshgrid command will do this for me with one line of code, but I have to do it with a nested for loop.

Any suggestions?

You're very close:

    for i=1:3
        for j=1:3
            X(i,j)=j;
            Y(i,j)=i;
        end
    end

Note that you're trying to fill a 2d matrix and you've already got 2 for loops... you can do without the while loop.

Is this what you're looking for?
