BCNLS

 
Solves nonlinear least-squares problems subject to bounds on the variables and
general linear constraints. The Jacobian is approximated using finite
differences. (Based on DQED by Hanson and Krogh.).
 
Classes  :  K1b2a . Linearly constrained nonlinear least squares
                  approximation
 
Type     : Fortran subroutine in IMSLM library.
Access   : Proprietary. Many implementations available.
Precision: Single.
 
Usage    : CALL BCNLS (FCN, M, N, MCON, C, LDC, BL, BU, IRTYPE, XLB, XUB, XGUESS,
           X, RNORM, ISTAT)
 
Details  : Documentation

Implementation of BCNLS from IMSLM on ITL

 
ITL:       Unix Workstation Network, National Institute of Standards and
           Technology (NIST), Gaithersburg, MD. Available to NIST staff.
 
Precision: Single. (Double: DBCNLS)
 
Access available only to NIST staff on internal Unix systems. They may access this
package provided the /itl tree is cross-mounted.
