> BTW, as we are on the subject: any plans for multidimensional interpolation?
Offhand, I'm not aware of any. We've not had a release in quite some time. We lack a maintainer. The bug backlog is nontrivial (https://savannah.gnu.org/bugs/?group=gsl). Make check is broken on at least one common platform. And many suggestions on the mailing list fall through the cracks. There's quite a bit to do before expanding the library's functionality. All that said, I'm sure patches would be welcome. - Rhys
