1.7
o negative values for stepmax (maximum stepsize) now imply no maximum stepsize.
The default for stepmax (maximum stepsize) -1.0 so there is no maximum stepsize.
o removed the Levenberg-Marquardt correction for ill-conditioned or singular jacobians.
The correction hardly ever gave sensible results. The algorithm now returns
an error condition when a Jacobian is singular or ill-conditioned.
1.6.1
o fixed several incomplete last lines
1.6
o corrected initialization bug
o corrected parameter error for Cauchy start in examples
o code cleaning to get rid of fortran statement labels
1.5
o corrected missing/superfluous closing brackets in nleqlsv.Rd
1.4
o correct horrible bug caused by typo in nwnwtn causing dgeqrf to be called
with an absurd value for the lwork argument. Typical fortran problem.
1.3
o use blocked Lapack QR routines.
Significant speed increase for larger n (500+) in most cases.
1.2
o corrected wrong name for the flag for checking an analytical jacobian in nleqslv.R
and the documentation
1.1
o the default initial trust region size is now set to the length of the Newton step
o corrected various errors in the documentation
* the termination codes were a muddle
* several elements of the return list were incorrectly named in the documentation
1.0
o initial version
