Re: Can anyone give an example of using leasqr?

[James Sherman Jr.]

There was a similar discussion on the use of leasqr here in the octave archives:

And I believe this, and the answers on that thread, answer your question.

Hi,

I was trying to do a non-linear curve fitting rouine (to get the parameters of a function using a given set of data) with Octave but didn't know how to use leasqr. If I defined a function f(x) = b*exp(-a*x), and had a set of data like

1    5.9
3    4.5
8    3.2
13  1.9

Can anybody tell me how to fit the function to the data to get the parameters a and b?

Thanks in advance.
