52e8c42a00 unsplit this test: was compiling 16 times the same thing! Need to find another way. Suggestion: should compile the stuff once into a binary library, or properly split into different tests with different code. 2010-06-11 07:15:34 -04:00

9962c59b56 * implement the corner() API change: new methods topLeftCorner() etc 
* get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway
* add topRows(), leftCols(), bottomRows(), rightCols()
* add corners unit-test covering all of that
* adapt docs, expand "porting from eigen 2 to 3"
* adapt Eigen2Support

* this is actually a boolean, not an int

67ce07ea83 matrix_function test: replace expm(A).inverse() by expm(-A) 
The latter is more stable. This fixes one of the issues with the test.
Also, make typedef's in MatrixFunctionReturnValue public; this is
necessary to get the test to compile.

b18f737aa1 Test matrix functions with matrices with clustered imaginary eivals. 
The idea is that these test MatrixFunction::swapEntriesInSchur(),
which is not covered by existing tests. This did not work out as
expected, but nevertheless it is a good test so I left it in.

Test matrix_function_3 now fails regularly because ComplexSchur
reaches the max number of iterations; further study needed.

2840ac7e94 big huge changes, so i dont remember everything. 
* renaming, e.g. LU ---> FullPivLU
* split tests framework: more robust, e.g. dont generate empty tests if a number is skipped
* make all remaining tests use that splitting, as needed.
* Fix 4x4 inversion (see stable branch)
* Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices.
* CMakeLists: more robust regexp to parse the version number
* misc fixes in unit tests

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()

* lot of external methods from cminpack are still used
* tests pass though they are unchanged (they use wrappers)

The first try fails, the second one passes, but with a very bad accuracy
(~4 digits only).
anyway, my aim is to check we do not change cminpack while portint, so i
keep this test.

b695113a81 Add all other file from cminpack/examples as tests. 
Important : one test was failing because cminpack-1.0.2 does x[3]=1. on x
which is of size 3. Probably because fortran indices are shifted wrt to C
indices and someone forgot to fix this one.

This is correct in this commit and this is the only change I've done on files
from cminpack examples.

(i've also reported the bug to cminpack author)
