* add Gael copyright lines on 2 more files * macro renaming: EIGEN_NDEBUG becomes EIGEN_NO_DEBUG as this is much better (and similar to Qt) and EIGEN_CUSTOM_ASSERT becomes EIGEN_USE_CUSTOM_ASSERT * protect Core header by a EIGEN_CORE_H

* Added ReferencableBit flag to known if coeffRef is available. (needed by the new product implementation) * Make the packet* members template to support aligned and unaligned access. This makes Block vectorizable. Combined with ReferencableBit, we should be able to determine at runtime (in some specific cases) if an aligned vectorization is possible or not. * Improved the new product implementation to robustly handle all cases, it now passes all the tests. * Renamed the packet version ei_predux to ei_preduxp to avoid name collision.

* Started support for unaligned vectorization. * Introduce a new highly optimized matrix-matrix product for large matrices. The code is still highly experimental and it is activated only if you define EIGEN_WIP_PRODUCT at compile time. Currently the third dimension of the product must be a factor of the packet size (x4 for floats) and the right handed side matrix must be column major. Moreover, currently c = a*b; actually computes c += a*b !! Therefore, the code is provided for experimentation purpose only ! These limitations will be fixed soon or later to become the default product implementation.

Added initial experimental support for explicit vectorization. Currently only the following platform/operations are supported: - SSE2 compatible architecture - compiler compatible with intel's SSE2 intrinsics - float, double and int data types - fixed size matrices with a storage major dimension multiple of 4 (or 2 for double) - scalar-matrix product, component wise: +,-,*,min,max - matrix-matrix product only if the left matrix is vectorizable and column major or the right matrix is vectorizable and row major, e.g.: a.transpose() * b is not vectorized with the default column major storage. To use it you must define EIGEN_VECTORIZE and EIGEN_INTEL_PLATFORM.

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
