Stéphane,
Yeah, but really badly conditionned compared to the above method which
is based on orthogonal tranformations (X=Q*R factorization). With your
below method you solve a linear system with X'*X matrix which has a
condition number which is the square of the condition number of the R

Dear All,
Trying to convert an old Matlab script to Scilab I miss the function
polyfit, which computes the coefficients of a polynomial that fits x-y
data using the least square method.
I found the following thread
