Question

Very Simple Question that i couldn’t find easily on the web so i thought i would ask here:

You can make a 1D linear array like this:

1:10 = 1 2 3 4 5 6 7 8 9 10
1:2:10 = 1 3 5 7 9

How can you easily initialise a 2D array ie.

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

and also the same thing but for columns:

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

Should be a command to do it in one line.

Answer 1

Alternatively i have learned that you can use meshgrid:

meshgrid(1:4, 1:4) =>

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

Thanks for the help and upvotes.
