I have a set of data that kills cspline (all output is nan). akima works
fine as far as I can tell. I don't know a whole lot about splines, but
the data set is not that erratic (at least to my eye).
Test case:
http://fuzzy.colorado.edu/spline_bug/test.c
http://fuzzy.colorado.edu/spline_bug/test.dat
I compiled test.c on my system with:
gcc test.c -lm -lgsl -latlas -lcblas -L/usr/lib/3dnow -g
valgrind ./a.out didn't show any memory errors.
I'm using the source tarball of gsl 1.5.
