[Help-gsl] 3D interpolation in GSL

[Sung, Raymond CW]

Dear GSL experts,

I have successfully installed GSL on my system and the interpolation function I 
was wanting to use works fine. However, as far as I understand, the function 
only works for 2D points but not 3D. Is this correct?

Is there an add-on to GSL that will allow interpolation of 3D coordinates?

Thanks in advance,

Raymond.
