I have a problem when I try to determine the parameter I wanted.The problem is:
I want to extract the values of a(a is depend on another parameter T),b from this function y=b*f(x/a(T)),but the function form of f(x) is unknow yet.Despite this,we can determine a and b like this:
first:
we can obtain different data sets with different T.
second:
we try different a and b.If a and b is the value we want,then we will see that all curves with different T will collapse into one curve.
But the question is I don't know how do this procedure by Origin 7.0.
Is there anyone who know how to settle the problem?
Thank you.
