Antw: Re: How to use Maxima to do a nonlinear fit?



** Reply Requested When Convenient **

Hello Robert, 

Thanks for your answer.
What is the benefit of lbfgs over lsquares?
Besides this, i do not know (till now) how to read data from a file into maxima-matrix. I saw an earlier post of R. Fateman describing an easy way to read data into a list, but not into a matrix. If put my values into a matrix maxima complains:

> Maxima encountered a Lisp error:

Thanks,
Robert

P.S.: I recognized that clisp is very slow compared to sbcl. under windows i estimated a factor of 400 = speed(sbcl) / speed(clisp) for generating & inverting random single-float matrices.
