aa3a7c3303 raw import of covar() : this is the last one, and we now do not depend on 
the cminpack library anymore.

16061a46db Now that the main algorithms are imported into eigen, we import subroutines 
used by those algorithms (aka "second level").

This is a row import : we copy/paste the files from cminpack and make
very few changes :
* template<Scalar> them (replace double)
* dpmpar() replaced by c++ standard equivalent
* abs/fabs/sqrt/min/max replaced by ei_* or std::*
* use eigen norms instead of enorm()

Important Notes:
* The use of stableNorm() was not enough in some cases, but using
  blueNorm() instead fixed the problems (some tests gave bad results,
  either in number of iterations or precision of the results)
* As a whole, the only test that changed is testNistMGH17() : it now takes
  some few steps less to get the same result. So this is a small improvement.

After this commit, the only remaining dependency from the cminpack
static library is 'covar', only used from the tests.

2e3d17c3ce be (hopefully) smarter with indices convention : we keep the c convention 
(0->n-1) as much as possible, and only convert at borders with
fortran-expecting methods, that will eventually dissapear.

8d2f6ad7e1 iwa is not really an argument, but just an old fashioned 'work array' : 
remove it from the eigen API
 2009-08-20 22:46:38 +02:00

9a876806e1 use eigen stableNorm() instead of cminpack 'enorm'. The results are mostly 
slightly better in tests (one test needs 15 iterations intead of 16, for
the same result). Some numerical results have improved slightly, too.

If one uses blueNorm() instead, an assert for 'overflow' is raised from
blueNorm()

f7cd4c8923 cleaning : wa1 used in 'covar' needs not be the same as in lmder* and all. 
it's just an old-fashioned way to re-use memory without allocation...

iterations instead of 7693 ;-)
the first test still fails though.
