greetings...

I am calling interpol and getting results that do not make sense.
The call is of the form

x=interpol(xin,yin,y2in)

I run two cases -
1. In the first case, xin, yin, and y2in each have 30 elements.
2. In the second case xin, yin, and y2in are each only 20 elements
long. They contain a portion of the the first cases's data
( the last 20 points ).

The problem is that the values of x in the 20 element
case are different than in the 30 element case even
though the xin, yin, and y2in arrays are the same
for the 20 input elements common to both cases.

I could be doing something stupid and just not seeing
it or the routine has a bug.

Anybody got a few words of wisdom?
