It was supposed to display as a mathematical graphic - sigma with bounds etc. It looked OK when I sent it, but somehow, the graphic became text. The text somehow displays the graphics in Internet Explorer for me but it got lost over e-mail. The graphic is at http://mathworld.wolfram.com/MovingAverage.html.
I think that this thread is a real good exorcise to test our reading skills in J. But it is not really fair to just put an expression out without any context or explanation. Mathematical expressions can be just as unreadable if the reader is not familiar with the field to which it relates. Oleg got it right off. So, given that most of us have a mathematical background, it is not hard to read if one has a background in mathematics. Here is the same thing in J. Is it hard to read or not? Is is easier than the mathematical version? It's certainly not as busy. +/\ % [ On Fri, Apr 4, 2008 at 12:11 PM, Raul Miller <[EMAIL PROTECTED]> wrote: > On Fri, Apr 4, 2008 at 2:05 PM, Don Guinn <[EMAIL PROTECTED]> wrote: > > Ok.
