How to do Linearization for Non-linear least squares?

  1. Nov 2, 2014 #1
    Hy
    I want to know how to make linearization for some function,...what should by in Non-linear least squares problems.
    In my book I have only this example how to do:

    Someone could me help how to do, some receipt of method what I need to do?

    Non-linear least squares problems was in Matlab:
    x = [ 1 2 3 4 5]
    y = [ 3.5 2 4 8]

    u = log(y)
    v = [ones(5,1), x']
    btr = x\u'
    beta0
    ....
    ....

    You have more x data values than corresponding y values?
