REQ: bounded & weighted least squares
I need to solve a linear least squares problem in which the different points
have specific weights. Also the adjustable coefficients need to be nonnegative.
Could somebody indicate a routine to solve this?
I also need to deal with at least 25 adjustable parameters and the same number
of independent variables.
A non linear solver it's ok.
Thanks in advance
