Objet: [mg11694] Data Extraction from List {{x1,y1}..{xn,yn}}where
##<x<##
Hello,
How might I extract a range of {x,y}from a list of data, so that I can
perform a linear fit between the point that meet the criterion of being
bewteen x_n and x_m.
In other words, fit a line to a part of the data that has #1<x<#2.
I have attempted to use the Select function but it requires me to
Flatten the data list first? And it results in giving me a list of just
the x values not the {x,y} pairs.
Any help is greatly appreciated.
Thanks,
Charles Koehler
