Re: [Jsbsim-devel] Multi-dimensional tables

Ah, yes - thanks for that. That explains it. JSBSim table lookups only do
gridded tables - not ungridded/sparse. There are a number of methods one
could take to fill in the blanks and IMHO it's better to do that offline.
It's sort of an art, in my experience.
