b09ebe01da * porting lmdif1 to eigen
* qtf was missing in lmdif signature (this is an output of the method)

8d2f6ad7e1 iwa is not really an argument, but just an old fashioned 'work array' :
remove it from the eigen API

a84dc9a5c1 coherency for scalar typename : use "Scalar" everywhere 2009-08-20 21:10:28 +02:00

df98e66019 oops fix hardcoded typename, which is actually provided as template
parameter

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()

6953cad81d remove unneeded "Eigen::", we already 'use' Eigen namespace 2009-08-19 20:06:34 +02:00

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)

703198a1a6 wrapper for chkder() : this was the last wrapper missing 2009-08-19 18:32:37 +02:00

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...

a6625f22d4 eigenize the test for lmder1, clean functor stuff.
(and check the tests still pass, of course, that's the whole point..)

f19eda7cf6 first test for a basic wrapper (and only wrapper!) for cminpack functions 2009-08-09 03:07:34 +02:00

d646d99366 Start of module "NonLinear". We start out of cminpack-1.0.2
(http://devernay.free.fr/hacks/cminpack.html)
The first test is adapted from the example/ directory.
Some stuff is hard coded for our initial tests.
