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.

ef582933c1 Proper fix for linking to the Qt libraries (and others) 
My initial fix was incorrect, the libraries must be quoted when being
passed to the add test macro, but must be unquoted when passed to the
target_link_libraries function.

2f0b4e1abc fix compilation with gcc 4.1. Indeed the path for recent gcc doesn't work with gcc 4.1, and looking at the implementation of vector in g++ 4.1, it was exactly our fallback case, so use that. 2009-08-21 12:16:37 -04:00

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.

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()

01622e9855 use machine precision from eigen instead of the one from cminpack. The test 
pass though they would not if using a value of 2.220e-16 (the real value
for 'double' is 2.22044604926e-16). How sensitive those tests are :)

fb54cfb013 import main files from cminpack as *.h files: 
* function names are changed by appending _template
* it uses basic templating : template<typename T>
* wrappers now use those versions instead of the ones from cminpack
* lot of external methods from cminpack are still used
* tests pass though they are unchanged (they use wrappers)
