Hi guys
Since I'm interested in the topic, I decided to look up the link
(https://help.scilab.org/datafit) on my phone.
I was unable to see the majority of the graphs on the right and I was
unable to zoom out.
I am able to 'replicate' it on the PC by narrowing the browser window,
by which the pictures disappear to the right, and there's no scroll bar
at the bottom.
I there any chance we could make the help pages phone-friendly?
Best regards,
Claus

Hello Federico, hello all,
Thanks for pointing this, it looks like there is some missing URL redirect
somewhere.
google "help scilab datafit" on a private navigation tab redirect to the 5.3.3
help page whereas https://help.scilab.org/datafit looks OK. I will try to update the
index to improve that, a related bug is #12746. See
https://bugzilla.scilab.org/show_bug.cgi?id=12746 for more information and discussion on
that topic, do not hesitate to contribute if you have some SEO knowledge.
Thanks,

Samuel:
Oh, this is embarrasing... I did a web search on non-linear fit and
somehow the top results always point at an outdated version (5.5.2) of
Scilab's documentation. I wonder why
Thanks, the new documentation is much better!

Dear All,
I'm trying to understand the function datafit.
The documentation says:
datafit is used for fitting data to a model. For a
given function
G(p,z), this function finds the best vector of parameters p for
approximating G(p,z_i)=0 for a set of measurement vectors z_i. Vector
p is found by minimizing
G(p,z_1)'WG(p,z_1)+G(p,z_2)'WG(p,z_2)+...+G(p,z_n)'WG(p,z_n)
I don't quite understand what is G(p,z_1)'WG(p,z_1). Are some
product signs * missing? Shouldn't it be G(p,z_1)'*W*G(p,z_1)? Are
these signs implied as in regular algebra notation?
Hello Federico,
Please see the documentation of the latest scilab release:
https://help.scilab.org/docs/6.1.0/en_US/datafit.html
