Lagrangian Interpolation for the HP-67 and HP-41C

[Namir]

Hi All,

I posted PDF files that contain Lagrangian interpolation programs for the HP-67 and HP-41C on my web site.. The HP-41C programs come in two versions. The accompanying algorithm pseudo-code explains the difference. The second version performs some of the calculations needed once and stores the intermediate results. When you perform interpolation, the program performs the needed calculations that involve the interpolated value of x. Therefore, you save time when you perform multiple interpolation with the same set of observations.

Thanks Namir!

It was good to meet you at HHC 2009 and I look forward to HHC 2010.

Same here. Any word on where and when HHC2010 will take place?

I haven't seen anything on it, but I'm sure that Richard, Joe, et al are working on it. ;)
