Hi, several times now I’ve needed a monotonic interpolation method. I saw some
posts from 2 years ago on this list from someone who implemented the method
from Steffen (1990), but it never got integrated into GSL and I couldn’t
contact that person.
I have now also implemented Steffen’s interpolation algorithm by copying the
existing akima.c file, but I am quite at a loss as to how to compile & test the
code. I normally use GSL installed from MacPorts which handles all the
compilation. I tried wget’ing the archive for GSL 1.6 and doing ./configure &&
make, but then I get errors about the PPC architecture (this is an x86 mac).
Could someone walk me through the steps for compiling & testing my steffen.c
code? My starting point:
- a fresh download and ./configure of GSL 1.6
- steffen.c placed in $GSL/interpolation
I don’t need people to write the test program itself, I just need to get to
something that will compile with “int main(void){return 0;}”. I can probably
handle the rest of the testing.
Thanks for any help,
Jean-François Caron
