hi,

I recently started using fortran. I have few questions.

will the polin2 subroutine in page 118 of NR FORTRAN 77 book help me handle 2D extrapolations?

And if you are familiar with the IMSL library, is there any subroutine there that handles 2D extrapolations. I have had no problems finding subroutines for interpolations.

Thank you in advance,
c.
