Is there a quick function to make an array whose elements are the sum of the row and column numbers?

Hello! This should hopefully be a quick and easy question:

Is there a function such that the output of Fun(4) would be:

[2 3 4 5;

3 4 5 6;

4 5 6 7;

5 6 7 8]

i.e. each element of the matrix is equal to its row number + its column number?

I cannot figure out a way to search this question in a concise manner, so I haven't been able to find anything. I know this is fairly simple to code, but I'm curious if there's an already existing function for this. Thanks!

You could probably do it using toeplitz

function out = Fun(n)
    out = (1:n) + (1:n).';
end

This worked. Sad to see there doesn't seem to be a built-in function for this. Thanks for the help, though :)

You're welcome!

That you can create your own function to do this is perhaps some consolation.
