[Help-gsl] Slight documentation error

[David Zaslavsky]

Hi,

I tried sending this out to gsl-discuss a while ago but it was never
approved, so I'm trying again and cc'ing it to help-gsl just in case.

Someone pointed out that the documentation for GSL 2.1 says that the 2D
interpolation requires equally spaced grids, but it actually doesn't. Or
to be more precise, it doesn't require that x[i] - x[i-1] == x[i+1] -
x[i] (and likewise for y), which is what most people would take "equally
spaced" to mean (I think). Could that be updated?

I can try to prepare a patch against the latest git revision, if that
would help.
