Analyze() operates on a number of global vectors and creates several new
global vectors, primarily based on the iteration vars of the for loops.  I
haven't included it yet cuz it's hard to simplify to a reasonable length for
this forum.  I'm happy to share it with those interested.  First, maybe I'll
see if I can implement Judd's ndgrid suggestion.

The primary reason why I have so many global vars is that analyze() and
another function have lots of inputs and/or outputs, and calling the
function would be cumbersome otherwise, so it's just easier to make them all
global.  I'm open to hearing any cautions regarding this.
