if you can define your formula as a function of wavelngth then you are
there
with y=fn(x
) you can generate "y" points for every "x" point you have
measured and then do your division....
You can use the formula node to generate "y" points from an "x" input,
you can also wire your co-efficints to the forumla node to make it
more flexible for different equations. To do limit checks you could
compare (using bollean opporators or numeric range restrictors) the
"y" values that come out for a "sensible range" and/or the "x" values
that go into the forumla. Wrap the entire thing in a for loop and you
can parse every "x" point in an input array to generate an output
array of "y" points. Afterwards you can divide you exisiting "y"
points array with these formula "y" points array as they map 1:1 for
the same "x".
This is just one appraoch, you could do the division in the for loop
or other varaitions.
