Solves nonlinear least squares problems with linear constraints and simple bounds using a quadratic-tensor local model. Some problems with nonlinear constraints can also be solved. Derivatives required. Forward or reverse communication. (See R.J. Hanson, SIAM J. Sci. Stat. Comput. 7 (1986) pp. 826-834.). Classes : K1b2a . Linearly constrained nonlinear least squares approximation K1b2b . Nonlinearly constrained nonlinear least squares approximation Type : Fortran subroutine in OPT package. Access : Some uses prohibited. Portable. Precision: Double. Note : Dependencies contains LINPACK and BLAS routines used by DQED.
