Dear Raul,
thanks for your writing, and also for directing this from the general to
the programming forum, where I probably should have posted it.
On the topic. I am afraid you misunderstood what I meant. The data
as a whole do not follow a simple trend, like lying on a line. they can
be even quite random. The task is to go from
X: 0 5 6 26
Y: 10 _10 80 100
to, say:
U: 0 5 10 15 20 25 30 NB. Equidistant mesh.
V: 10 _10 84 90 94 99 104 NB. Linear interpolation and extrapolation when
needed.
NB. The numbers with U>5 are rounded here for
readability.
NB. If U=26 were, by chance, in the mesh,
NB. the value would be (exactly) 100.
(This is not what the data look like in reality, but as an example it
could suffice.)
Thanks once more!
Ruda
