* 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.

hehe, the complicated nesting scheme in Flagged in the previous commit was a sign that we were doing something wrong. In fact, having NestByValue as a special case of Flagged was wrong, and the previous commit, while not buggy, was inefficient because then when the resulting NestByValue xpr was nested -- hence copied -- the original xpr which was already nested by value was copied again; hence instead of 1 copy we got 3 copies. The solution was to ressuscitate the old Temporary.h (renamed NestByValue.h) as it was the right approach.

2008-03-03 18:52:44 +08:00
#include "src/Core/CwiseUnaryOp.h"
Fix a couple of issue with the vectorization. In particular, default ei_p* functions are provided to handle not suported types seemlessly. Added a generic null-ary expression with null-ary functors. They replace Zero, Ones, Identity and Random.
2008-04-25 02:35:39 +08:00
#include "src/Core/CwiseNullaryOp.h"
* added optimized paths for matrix-vector and vector-matrix products (using either a cache friendly strategy or re-using dot-product vectorized implementation) * add LinearAccessBit to Transpose
2008-07-10 06:30:18 +08:00
#include "src/Core/Dot.h"
* find the proper way of nesting the expression in Flagged: finally that's more subtle than just using ei_nested, because when flagging with NestByValueBit we want to store the expression by value already, regardless of whether it already had the NestByValueBit set. * rename temporary() ----> nestByValue() * move the old Product.h to disabled/, replace by what was ProductWIP.h * tweak -O and -g flags for tests and examples * reorder the tests -- basic things go first * simplifications, e.g. in many methoeds return derived() and count on implicit casting to the actual return type. * strip some not-really-useful stuff from the heaviest tests
2008-05-28 12:38:16 +08:00
#include "src/Core/Product.h"
* split Product to a DiagonalProduct template specialization to optimize matrix-diag and diag-matrix products without making Product over complicated. * compilation fixes in Tridiagonalization and HessenbergDecomposition in the case of 2x2 matrices. * added an Orientation2D small class with similar interface than Quaternion (used by Transform to handle 2D and 3D orientations seamlessly) * added a couple of features in Transform.

#include "src/Core/SolveTriangular.h"
* Big change in Block and Map: - added a MapBase base xpr on top of which Map and the specialization of Block are implemented - MapBase forces both aligned loads (and aligned stores, see below) in expressions such as "x.block(...) += other_expr" * Significant vectorization improvement: - added a AlignedBit flag meaning the first coeff/packet is aligned, this allows to not generate extra code to deal with the first unaligned part - removed all unaligned stores when no unrolling - removed unaligned loads in Sum when the input as the DirectAccessBit flag * Some code simplification in CacheFriendly product * Some minor documentation improvements

2008-06-23 18:32:48 +08:00
#include "src/Core/Sum.h"
* 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

No support for xpr on the right side for the moment. * Added support for assertion checking.
