ajb Posted November 2, 2008 Share Posted November 2, 2008 Does anyone know of any free software that is good at fitting curves to data? I have tried Mathematica, but it does not seem to do the job I need as the curve is highly non-polynomial. I should also add that such data analysis is outside my normal work and this is a favour for someone. Link to comment Share on other sites More sharing options...
the tree Posted November 11, 2008 Share Posted November 11, 2008 If it's for something simple, then Graph is surprisingly effective, or a least sufficiently quick. Link to comment Share on other sites More sharing options...
ajb Posted November 11, 2008 Author Share Posted November 11, 2008 Thank you. I will have a look at that when I get round to it. Link to comment Share on other sites More sharing options...

ajb Posted November 11, 2008 Author Share Posted November 11, 2008 R did cross my mind also. Thanks Klay. Link to comment Share on other sites More sharing options...
Klaynos Posted November 11, 2008 Share Posted November 11, 2008 I'm a big advocate of R... octave might also be worth a look, very very similar to matlab, but I've not used eitehr much for a few years... Link to comment Share on other sites More sharing options...
