i need to perform nested sums such as Sum[f, {i,imin,imax},{j, jmin, jmax}, ...{}]. In each nest the new index is a function of the previous and the max values vary. Also at the beginning I do not know how long a nest I need. I can't come up with anything that works. I could construct a list {{i,imin,imax},{j, jmin, jmax}, ...{}} but "Sum" doen't know what to do with the outside braces{...}.
ANy suggestions would be much appreciated.
