missing ones, etc.
(note that const qualifiers are set by internall::nested)

Also fix some typos.

a standard math function using std:: but rather put a using std::foo before and simply call foo:
using std::max;
max(a,b);

As discussed on the list (too long to explain here).

* Now completely generic so all standard integer types (like char...) are supported.
** add unit test for that (integer_types).
* NumTraits does no longer inherit numeric_limits
* All math functions are now templated
* Better guard (static asserts) against using certain math functions on integer types.
|
| | |
|

* 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
|

it never made very precise sense. but now does it still make any?
|
| |
|
|
|
| |
* fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated"
warning which I haven't looked much into

- in matrix-matrix product, static assert on the two scalar types to be the same.
- Similarly in CwiseBinaryOp. POTENTIALLY CONTROVERSIAL: we don't allow anymore binary
ops to take two different scalar types. The functors that we defined take two args
of the same type anyway; also we still allow the return type to be different.
Again the reason is that different scalar types are incompatible with vectorization.
Better have the user realize explicitly what mixing different numeric types costs him
in terms of performance.
See comment in CwiseBinaryOp constructor.
- This allowed to fix a little mistake in test/regression.cpp, mixing float and double
- Remove redundant semicolon (;) after static asserts

can be seen in Eigen/src/Core/Cwise.h.

- works for complex
- allows direct access to the matrix R
* removed the scale by the matrix dimensions in MatrixBase::isMuchSmallerThan(scalar)
|

tends to show L2 norm works very well here.
(the legacy implementation is still available via a preprocessor token
to allow further experiments if needed...)
|
| |
|
|
| |
(see notes in Core/util/StaticAssert.h for details)

* rename OperatorEquals -> Assign
* move Util.h and FwDecl.h to a util/ subdir

ei_xpr_copy to evaluate args when needed. Had to introduce an ugly
trick with ei_unref as when the XprCopy type is a reference one can't
directly access member typedefs such as Scalar.

to disable eigen's asserts without disabling one's own program's
asserts. Notice that Eigen code should now use ei_assert()
instead of assert().
* Remove findBiggestCoeff() as it's now almost redundant.
* Improve echelon.cpp: inner for loop replaced by xprs.
* remove useless "(*this)." here and there. I think they were
first introduced by automatic search&replace.
* fix compilation in Visitor.h (issue triggered by echelon.cpp)
* improve comment on swap().

Finally the importing macro is named EIGEN_BASIC_PUBLIC_INTERFACE
because it does not only import the ei_traits, it also makes the base class
a friend, etc.

template parameter "Scalar" is removed. This is achieved by introducting a
template <typename Derived> struct Scalar to achieve a forward-declaration of
the Scalar typedefs.

fragile. also fix compilation with g++ 4.3.

- complete documentation
- add TODO
- update copyright years
|
| |
|
|
| |
doxygen likes it and this fixes compilation on ICC.

- the static constants are private again in the Derived classes
- more documentation and code snippets
- new isDiagonal() method
|

Honor this preference in operator=.
- add several methods to the API
- rework API for diagonal matrices
- add benchmarking code
