Not sure what you meant by slow but the example clocked in at 2ms real time 
and did not show on the millisecond user/system clocks.

Sorta looks like a steepest descent routine with no analysis from derivatives 
so it is likely to be sluggish.

So much for Dozier's idea of a speedy method.  ;-)

I stupidly missed all the control in the file so had to do about three whacks 
at getting it to compile.  Once the junk was removed it went fine.
