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



> yes. but i did not get very far as you can see here. i think i need to know how to read data from file to matrix. 

Try the 'numericalio' package, 'read_matrix' is the function you need.

If data.txt is of the form

280 0 0 0.251
260 0 0 0.237
240 0 0 0.231
220 0 0 0.229
....

write:

load(numericalio)$
m: read_matrix("path_to/data.txt");
