a35586504e cleaning f2c mess / trivial stuff 2009-08-22 07:14:17 +02:00
Thomas Capricelli
aa3a7c3303 raw import of covar() : this is the last one, and we now do not depend on 
the cminpack library anymore.
 2009-08-22 06:44:41 +02:00
Thomas Capricelli
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.

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()

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 :)

* 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)

0170eb0dbe add an auto-diff module in unsupported. it is similar to adolc's forward 
mode but the advantage of using Eigen's expression template to compute
the derivatives (unless you nest an AutoDiffScalar into an Eigen's
matrix).

44a527dfa5 * classify and sort the doxygen "related pages" 
by tweaking the filename and adding 2 categories:
   Troubleshooting and Advanced
* use the EXCLUDE_SYMBOLS to clean the class list
  (insteaded of a homemade bash script)
* remove the broken "exemple list"
* re-structure the unsupported directory as mentionned in the ML and
  integrate the doc as follow:
  - snippets of the unsupported directory are directly imported from the
    main snippets/CMakefile.txt (no need to duplicate code)
  - add a top level "Unsupported modules" group
  - unsupported modules have to defined their own sub group and nest it
    using \ingroup Unsupported_modules
  - then a pair of //@{ //@} will put everything in the submodule
  - this is just a proposal !
