RNLIN

 
Fit a nonlinear regression model.
 
Classes  :  K1b1a1 . Unconstrained nonlinear least squares approximation by
                   smooth functions, user provides no derivatives
            K1b1a2 . Unconstrained nonlinear least squares approximation by
                   smooth functions, user provides first derivatives
            L8e1 .   Nonlinear least squares regression (i.e., y = F(X,b))

Implementation of RNLIN from IMSLS on ITL

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