NSF

 
Solve separable nonlinear least squares problem (i.e., one with both linear and
nonlinear parameters). Derivatives are approximated using finite
differences. Uses variable-projection technique to eliminate linear
parameters, thus obtaining a simpler nonlinear least squares problem.
 
Classes  :  K1b1a1 . Unconstrained nonlinear least squares approximation by
                   smooth functions, user provides no derivatives
 
Type     : Fortran subroutine in PORT library (NL2OPT sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Single.
 
Usage    : CALL NSF (N, P, L, ALF, C, Y, CALCA, INC, IINC, IV, LIV, LV, V, UIPARM,
           URPARM, UFPARM)
