612350e3f8 * Added a generic *redux* mini framework allowing custom redux operations
as well as partial redux (vertical or horizontal redux).
   Includes shortcuts for: sum, minCoeff and maxCoeff.
   There is no shortcut for the partial redux.

 * Added a generic *visitor* mini framework. A visitor is a custom object
   sequentially applied on each coefficient with knowledge of its value and
   coordinates.
   It is currentlly used to implement minCoeff(int*,int*) and maxCoeff(int*,int*).
   findBiggestCoeff is now a shortcut for "this->cwiseAbs().maxCoeff(i,j)"

 * Added coeff-wise min and max.
 * fixed an issue with ei_pow(int,int) and gcc < 4.3 or ICC

fb3438e609 - expand MathFunctions.h to provide more functions, like exp, log...
- add cwiseExp(), cwiseLog()...
   --> for example, doing a gamma-correction on a bitmap image stored as
       an array of floats is a simple matter of:
         Eigen::Map<VectorXf> m = VectorXf::map(bitmap,size);
         m = m.cwisePow(gamma);
- apidoc improvements, reorganization of the \name's
- remove obsolete examples
- remove EIGEN_ALWAYS_INLINE on lazyProduct(), it seems useless.

fe569b060c get rid of MatrixRef, simplifications. 2008-03-13 20:36:01 +00:00

afc64f3332 a lot of renaming
internal classes: AaBb -> ei_aa_bb
IntAtRunTimeIfDynamic -> ei_int_if_dynamic
unify UNROLLING_LIMIT (there was no reason to have operator= use
a higher limit)
etc...

2ee68a074e generalized ei_traits<>.
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.

01572b9f54 big change: MatrixBase only takes one template parameter "Derived", the
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.

721626dfc5 * Added support for a comma initializer: mat.block(i,j,2,2) << 1, 2, 3, 4;
If the number of coefficients does not match the matrix size, then an assertion is raised.
  No support for xpr on the right side for the moment.

* Added support for assertion checking. This allows to test that an assertion is indeed raised
  when it should be.

* Fixed a mistake in the CwiseUnary example.

138aad0ed0 * coefficient wise operators are more generic, with controllable result type.
- compatible with current STL's functors as well as with the extention proposal (TR1)
 * thanks to the above, Cast and ScalarMultiple have been removed
 * benchmark_suite is more flexible (compiler and matrix size)

f65cca5d1d * Eigen compiles with any GCC versions from, at least, 3.3 without the previous ugly hack :)
* Renamed the scalar functors with the "Scalar" prefix (instead of "Cwise")

255689231d * Added generic unary operators (replace Opposite and Conjugate)
* functor templates are not template template parameter anymore
   (this allows to make templated functors !)
 * Main page: extented compiler discussion
 * A small hack to support gcc 3.4 and 4.0 (see the main page)
 * Fix a cast type issue in Cast
 * Various doxygen updates (mainly Cwise stuff and added doxygen groups
   in MatrixBase to split the huge memeber list, still not perfect though)
 * Updated Gael's email address

a2f8d4be6a Patch by Gael Guennebaud: coeff-wise binary operators.
This unifies + and - and moreover this patch introduces
coeff-wise * and / based on this. Also, corresponding test.
