Hi!

Can anyone tell me how to do this in matlab? I've tried using 3 for loops but I am getting the wrong answer. My range is from -2 to 2.

Here is what I want to get:

… and so on and so forth.

Thanks a lot!

Answer 1

Try this:

[X,Y,Z] = ndgrid(-2:2);
Out = [Z(:),Y(:),X(:)]

producing:

Out =
    -2    -2    -2
    -2    -2    -1
    -2    -2     0
    -2    -2     1
    -2    -2     2
    -2    -1    -2
    -2    -1    -1
    -2    -1     0
    -2    -1     1
    -2    -1     2
    -2     0    -2
    -2     0    -1
    -2     0     0
    -2     0     1
    -2     0     2
         etc.
