DNSG

 
Solve separable nonlinear least squares problem (i.e., one with both linear and
nonlinear parameters). User supplies derivatives. Uses variable-projection
technique to eliminate linear parameters, thus obtaining a simpler nonlinear
least squares problem.
 
Classes  :  K1b1a2 . Unconstrained nonlinear least squares approximation by
                   smooth functions, user provides first derivatives
 
Type     : Fortran subroutine in PORT library (NL3OPT sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Double.
 
Usage    : CALL DNSG (N, P, L, ALF, C, Y, CALCA, CALCB, INC, IINC, IV, LIV, LV, V,
           UIPARM, URPARM, UFPARM)
