68168e9eae MatrixFunctions: replace eval() by nested. 
This eliminates an unnecessary copy in some situations, e.g. Map.

42e2578ef9 the min/max macros to detect unprotected min/max were undefined by some std header, 
so let's declare them after and do the respective fixes ;)

d23845c4cc Fix typo ('using namespace' instead of 'using'). 2011-05-26 09:52:36 +01:00
Gael Guennebaud
87ac09daa8 Simplify the use of custom scalar types, the rule is to never directly call a standard math function using std:: but rather put a using std::foo before and simply call foo: 
using std::max;
max(a,b);

307c428253 Move documentation of MatrixBase methods in MatrixFunctions to module page. 
I think that because MatrixFunctions is in unsupported/ and MatrixBase is
not, doxygen does not include the MatrixBase methods defined and documented
in the MatrixFunctions module with the other MatrixBase methods. This is a
kludge, but at least the documentation is not lost.

f54a2a0484 Add support for general matrix functions. 
This does the job but it is only a first version. Further plans:
improved docs, more tests, improve code by refactoring, add convenience
functions for sine, cosine, sinh, cosh, and (eventually) add the matrix
logarithm.

d088ee35f6 Added to possibility to compile unit tests at maximum warning level. 
Silenced (amongst others) many conversion related warnings.

2026ea7ff2 Coax doxygen in producing better docs for MatrixFunctions. 
The //@{ ... //@} in unsupported/Eigen/MatrixFunctions for some reason
caused doxygen to list the constructor of the MatrixExponential class
as a separate function in the MatrixFunctions module without any reference
to the class; very confusing.

39ceba409b Various improvements to the docs for unsupported. 
* Enable compilation of examples for unsupported.
* Fix use of std::vector in BVH example.
* Add an example for the matrix exponential.
* Bug fixes in unsupported/doc/{examples,snippets}/CMakeLists.txt .

66534b782c Some of our unit tests require mathematical constants and thus we rely on non-ansi code. 
It seems as if the new standard removed pow(T,int).
M_PIL is only defined when _GNU_SOURCE is defined.

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

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?
