Sorry I spent a good deal of time looking this up but I think the keywords are too common to do a good search. I am talking about matrices of mxn dimensions where i is row index and j is column.

I am trying to create a matrix whose entries are f(j-i), where f is a function call that I will choose.

I figured it would be good to start by making a matrix whose entries are (j-i).

I can easily make a row or a column vector using 1:n or 1:m, but that's as far as I can get. Any ideas?

Am I missing a command to assign a matrix element a function of its row and column indices?

No "removethis" in my e-mail, naturally.


Would MESHGRID help?
