Hi,
After importing a CSV I have a list of coordinates/corresponding function values as {x, y, z, f(x,y,z)}, but Interpolation expects a list structured as {{x, y, z}, f(x,y,z)}. What is the easiest way to convert it to that format?
Thanks, Gijsbert
One method that is most general, and easy to see what is happening is:
newlist = {{#1, #2, #3}, #4}& @@@ oldlist;
But solutions with TakeDrop or Table and so on are also possible:
newlist = Table[{p[[;;3]], p[[4]]}, {p,oldlist}]
