0a5c2d8a54 fix misc warnings, more importantly when NDEBUG is defined, assert() is a
nop.

5a36f4a8d1 Propagate all five matrix template parameters to members and temporaries of decomposition classes. One particular advantage of this is that decomposing matrices with max sizes known at compile time will not allocate.
NOTE: The ComplexEigenSolver class currently _does_ allocate (line 135 of Eigenvalues/ComplexEigenSolver.h), but the reason appears to be in the implementation of matrix-matrix products, and not in the decomposition itself.
The nomalloc unit test has been extended to verify that decompositions do not allocate when max sizes are specified. There are currently two workarounds to prevent the test from failing (see comments in test/nomalloc.cpp), both of which are related to matrix products that allocate on the stack.

7c98c04412 add reconstructedMatrix() to LLT, and LUs
=> they show that some improvements have still to be done

3d066f4bc7 LDLT:
* fix bug thanks to Ben Goodrich: we were terminating at the wrong place, leaving some matrix coefficients with wrong values.
* don't use Higham's formula here: we're not trying to be rank-revealing.

871698d3aa Introduced NestParentByRefBit and NestByRefBit - this should fix temporaries related to nested products.
Fixed a few typos and a few warnings.

e3d890bc5a Another big refactoring change:
* add a new Eigen2Support module including Cwise, Flagged, and some other deprecated stuff
* add a few cwiseXxx functions
* adapt a few modules to use cwiseXxx instead of the .cwise() prefix

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

92480ffd26 * Introduce make targets btest (build tests), blas (build blas lib), demos (build demos).
* remove EIGEN_BUILD_TESTS and siblings
* add summary at the end of cmake run, hopefully not too verbose
* fix build of quaternion demo
* kill remnants of old binary library option

ea23f36c78 * change the nesting order of adjoint_return_type to
1 - make it easier to catch conjugate expressions
 2 - make sure there is no unecessary copy (we had NestByValue<Derived> which seems to be very bad)
* update eigensolver wrt recent changes

544888e342 add a generic mechanism to copy a special matrix to a dense matrix so that
we don't need to add other specialization of MatrixBase::operator=, Matrix::=,
and Matrix::Matrix(...)

1aea45335f * bybye Part, welcome TriangularView and SelfAdjointView.
* move solveTriangular*() to TriangularView::solve*()
* move .llt() to SelfAdjointView
* add a high level wrapper to the efficient selfadjoint * vector product
* improve LLT so that we can specify which triangular part is meaningless
=> there are still many things to do (doc, cleaning, improve the matrix products, etc.)

2f45eeb0c6 More Cholesky fixes.
* Cholesky decs are NOT rank revealing so remove all the rank/isPositiveDefinite etc stuff.
* fix bug in LLT: s/return/continue/
* introduce machine_epsilon constants, they are actually needed for Higman's formula determining
  the cutoff in Cholesky. Btw fix the page reference to his book (chat with Keir).
* solve methods always return true, since this isn't a rank revealing dec. Actually... they already did always return true!! Now it's explicit.
* updated dox and unit-test

a1ba995f05 Many improvements in LLT and LDLT:
* in LDLT, support the negative semidefinite case
* fix bad floating-point comparisons, improves greatly the accuracy of methods like
  isPositiveDefinite() and rank()
* simplifications
* identify (but not resolve) bug: claim that only triangular part is used, is inaccurate
* expanded unit-tests

70c0174bf9 * allows fixed size matrix with size==0 (via a specialization of
MatrixStorage returning a null pointer). For instance this is very
  useful to make Tridiagonalization compile for 1x1 matrices
* fix LLT and eigensolver for 1x1 matrix
