Driver for NIST separable nonlinear least squares problem set #4
Description
The source file compjplJ.f90 is a driver for solving the 27 nonlinear least squares problems that are presented at the NIST site
https://www.itl.nist.gov/div898/strd/nls/nls_main.shtml
using the MATH77 routine DNLSGU. This file is to be compiled and linked with the subroutine files
dnlsgu.f, divset.f, drnsg.f, drn2g.f, dq7rfh.f, idam.f, amach.f
of the MATH77 library from JPL.
To run one of the NIST problems, for example, Nelson, enter the command
echo Nelson.dat | ./compjplJ
The 27 data files and the driver source file can be obtained in a zip file:

Apology: I am not used to adding content to Github, so I am providing a link to a Zip file with the content that is suggested for addition to the math77 Github.
