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
Regards
