------- Additional comments from [EMAIL PROTECTED] Tue Jul 10 12:54:35 +0000 2007 ------- I think mathematically it is not valid. If you have n=2 and k=4 for example (2+n-k=2+2-4=0) then you have 3 points and try to approximate with polynoms of degree 3. But that is not possible, because a polynom of degree 3 has 4 coefficients and therefore you need 4 points to calculate them. Even with fMaxCurveParam = 0, we will not enter the outer loop, because the stop-condition is false immediately. Therefore it will not raise an error as far as I see, but you get the last input point into the output. So the question seems to be, whether you want an empty output as in my version or 1 output point as in your version. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
