I want to do a least squares fit to the values around a matrix diagonal including the diagonal itself.

Actually the post went out prematurely. But it help me get a clearer picture of what I want to do. So let me ask another question. How do I query the values in a matrix surrounding the diagonal? That is for each row and column such that sqrt(p^2 + q^2) < n^2 elements from the diagonal besides a loop.

? You are looking for a quarter-circle centered just outside the upper left corner, with radius n ?
