* * Much better, consistent error msgs when mixing different scalar types:Gravatar Benoit Jacob2008-12-03
| | | | | | | | | | | | | - 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

* improve assertion checking in productGravatar Gael Guennebaud2008-10-25
|
* As discussed on ML:Gravatar Gael Guennebaud2008-10-24
| | | | | | | | | | * remove the automatic resizing feature of operator = * add function Matrix::set() to be used when the previous behavior is wanted * the default constructor of dynamic-size matrices now creates a "null" matrix (data=0, rows = cols = 0) instead of a 1x1 matrix * fix UnixX typos ;)
* Solve the issue found by Timothy in solveTriangular:Gravatar Gael Guennebaud2008-10-13
| | | | | | => row-major rhs are now evaluated to a column-major temporary before the computations. Add solveInPlace in Cholesky*

|
* * remove LargeBit and related stuffGravatar Gael Guennebaud2008-08-23
| | | | | | | * replaced the Flags template parameter of Matrix by StorageOrder and move it back to the 4th position such that we don't have to worry about the two Max* template parameters * extended EIGEN_USING_MATRIX_TYPEDEFS with the ei_* math functions
* * Fix CMakeLists.txt issue with SVDGravatar Gael Guennebaud2008-08-20
| | | | * Fix on stack memory allocation issues
* Various compilation fixes for MSVC 9. All tests compile but someGravatar Gael Guennebaud2008-08-19
| | | | still fail at runtime in ei_aligned_free() (even without vectorization).
* * doc improvements in Cwise and PartialRedux:Gravatar Benoit Jacob2008-08-19
| | | | | | | | | - 33 new snippets - unfuck doxygen output in Cwise (issues with function macros) - more see-also links from outside, making Cwise more discoverable * rename matrixNorm() to operatorNorm(). There are many matrix norms (the L2 is another one) but only one is called the operator norm. Risk of confusion with keyword operator is not too scary after all.
* only use alloca on linux. Use malloc on other platforms. Needed for mingwGravatar Benoit Jacob2008-08-18
| | | | compatibility.
* fix two perf issues in product.Gravatar Gael Guennebaud2008-08-03
| | | | | fix positive definite test in Cholesky. remove #include <cstring> in CoreDeclaration.
* fix compile errors with gcc 4.3: unresolved func call toGravatar Benoit Jacob2008-08-03
| | | | ei_cache_friendly_product, and undeclared memcpy
* Added a ei_palign function align a packet from two others.Gravatar Gael Guennebaud2008-08-03
| | | | | This allows much faster code dealing with unligned as in the updated matrix-vector product functions.
* fix some internal asserts in CacheFrinedlyProductGravatar Gael Guennebaud2008-07-27
|
* Fix a couple issues introduced in the previous commit:Gravatar Gael Guennebaud2008-07-26
| | | | | * removed DirectAccessBit from Part * use a template specialization in inverseProduct() to transform a Part xpr to a Flagged xpr
* add some static asserts, use them, fix gcc 4.3 warning in Product.h.Gravatar Benoit Jacob2008-07-19
|
* * Fix a couple of issues related to the recent cache friendly productsGravatar Gael Guennebaud2008-07-19
| | | | | | | * Improve the efficiency of matrix*vector in unaligned cases * Trivial fixes in the destructors of MatrixStorage * Removed the matrixNorm in test/product.cpp (twice faster and that assumed the matrix product was ok while checking that !!)
* Optimization: added super efficient rowmajor * vector product (and vector * ↵Gravatar Gael Guennebaud2008-07-13
| | | | | | | | colmajor). It basically performs 4 dot products at once reducing loads of the vector and improving instructions scheduling. With 3 cache friendly algorithms, we now handle all product configurations with outstanding perf for large matrices.
* * Optimization: added a specialization of Block for xpr with DirectAccessBitGravatar Gael Guennebaud2008-07-12
| | | | * some simplifications and fixes in cache friendly products
* Add a *very efficient* evaluation path for both col-major matrix * vectorGravatar Gael Guennebaud2008-07-12
| | | | | | and vector * row-major products. Currently, it is enabled only is the matrix has DirectAccessBit flag and the product is "large enough". Added the respective unit tests in test/product/cpp.
* * added optimized paths for matrix-vector and vector-matrix productsGravatar Gael Guennebaud2008-07-09
| | | | | | (using either a cache friendly strategy or re-using dot-product vectorized implementation) * add LinearAccessBit to Transpose
* * do the ActualPacketAccesBit change as discussed on listGravatar Benoit Jacob2008-07-04
| | | | | * add comment in Product.h about CanVectorizeInner * fix typo in test/product.cpp
* * fix compilation issue in ProductGravatar Gael Guennebaud2008-07-02
| | | | | * added some tests for product and swap * overload .swap() for dynamic-sized matrix of same size
* * added innerSize / outerSize functions to MatrixBaseGravatar Gael Guennebaud2008-06-28
| | | | | | | * added complete implementation of sparse matrix product (with a little glue in Eigen/Core) * added an exhaustive bench of sparse products including GMM++ and MTL4 => Eigen outperforms in all transposed/density configurations !
* various work on the Sparse module:Gravatar Gael Guennebaud2008-06-26
| | | | | | | | | | | | | | | | * added some glue to Eigen/Core (SparseBit, ei_eval, Matrix) * add two new sparse matrix types: HashMatrix: based on std::map (for random writes) LinkedVectorMatrix: array of linked vectors (for outer coherent writes, e.g. to transpose a matrix) * add a SparseSetter class to easily set/update any kind of matrices, e.g.: { SparseSetter<MatrixType,RandomAccessPattern> wrapper(mymatrix); for (...) wrapper->coeffRef(rand(),rand()) = rand(); } * automatic shallow copy for RValue * and a lot of mess ! plus: * remove the remaining ArrayBit related stuff * don't use alloca in product for very large memory allocation
* change derived classes methods from "private:_method()"Gravatar Benoit Jacob2008-06-26
| | | | | | | | to "public:method()" i.e. reimplementing the generic method() from MatrixBase. improves compilation speed by 7%, reduces almost by half the call depth of trivial functions, making gcc errors and application backtraces nicer...
* * add bench/benchVecAdd.cpp by Gael, fix crash (ei_pload on non-aligned)Gravatar Benoit Jacob2008-06-26
| | | | | | | | | | | | * introduce packet(int), make use of it in linear vectorized paths --> completely fixes the slowdown noticed in benchVecAdd. * generalize coeff(int) to linear-access xprs * clarify the access flag bits * rework api dox in Coeffs.h and util/Constants.h * improve certain expressions's flags, allowing more vectorization * fix bug in Block: start(int) and end(int) returned dyn*dyn size * fix bug in Block: just because the Eval type has packet access doesn't imply the block xpr should have it too.
* * implement slice vectorization. Because it uses unalignedGravatar Benoit Jacob2008-06-22
| | | | | | | | | packet access, it is not certain that it will bring a performance improvement: benchmarking needed. * improve logic choosing slice vectorization. * fix typo in SSE packet math, causing crash in unaligned case. * fix bug in Product, causing crash in unaligned case. * add TEST_SSE3 CMake option.
* * more cleaning in ProductGravatar Gael Guennebaud2008-06-19
| | | | | | * make Matrix2f (and similar) vectorized using linear path * fix a couple of warnings and compilation issues with ICC and gcc 3.3/3.4 (cannot get Transform compiles with gcc 3.3/3.4, see the FIXME)
* * refactoring of Product:Gravatar Gael Guennebaud2008-06-19
| | | | | | | | * use ProductReturnType<>::Type to get the correct Product xpr type * Product is no longer instanciated for xpr types which are evaluated * vectorization of "a.transpose() * b" for the normal product (small and fixed-size matrix) * some cleanning * removed ArrayBase
* fix two bugs dicovered by the previous commit.Gravatar Gael Guennebaud2008-06-16

* * Block: row and column expressions in the inner directionGravatar Benoit Jacob2008-06-16
| | | | | | | | | now have the Like1D flag. * Big renaming: packetCoeff ---> packet VectorizableBit ---> PacketAccessBit Like1DArrayBit ---> LinearAccessBit
* * Big rework of Assign.h:Gravatar Benoit Jacob2008-06-16
| | | | | | | | | | | | | | | ** Much better organization ** Fix a few bugs ** Add the ability to unroll only the inner loop ** Add an unrolled path to the Like1D vectorization. Not well tested. ** Add placeholder for sliced vectorization. Unimplemented. * Rework of corrected_flags: ** improve rules determining vectorizability ** for vectors, the storage-order is indifferent, so we tweak it to allow vectorization of row-vectors. * fix compilation in benchmark, and a warning in Transpose.
* * split Product to a DiagonalProduct template specializationGravatar Gael Guennebaud2008-06-15
| | | | | | | | | | 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.
* Started a Transform class in the Geometry module to representGravatar Gael Guennebaud2008-06-15
| | | | | homography. Fix indentation in Quaternion.h
* * make the _Flags template parameter of Matrix default to the correctedGravatar Benoit Jacob2008-06-13
| | | | | | | | | flags. This ensures that unless explicitly messed up otherwise, a Matrix type is equal to its own Eval type. This seriously reduces the number of types instantiated. Measured +13% compile speed, -7% binary size. * Improve doc of Matrix template parameters.
* * move some compile time "if" to their respective unroller (assign and dot)Gravatar Gael Guennebaud2008-06-07
| | | | | * fix a couple of compilation issues when unrolling is disabled * reduce default unrolling limit to a more reasonable value
* fix eigenvectors computations :)Gravatar Gael Guennebaud2008-06-03
|
* meagre outcome for so much time spent!Gravatar Benoit Jacob2008-06-01
| | | | | | * fix inverse() bug discovered by Gael's test * fix warnings introduced by the new Diagonal stuff * update Doxyfile to v1.5.6
* added optimized matrix times diagonal matrix product via Diagonal flag shortcut.Gravatar Gael Guennebaud2008-05-31
|
* simply a bit the basic product moving dynamic loopsGravatar Gael Guennebaud2008-05-31
| | | | | to the corresponding special case of the unrollers. the latter ones are therefore re-named *product_impl.
* * replace compile-time-if by meta-selector in Assign.hGravatar Gael Guennebaud2008-05-31
| | | | | as it speed up compilation. * fix minor typo introduced in the previous commit
* Added ArrayBit to get the ability to manipulate a Matrix like a simple scalar.Gravatar Gael Guennebaud2008-05-29
| | | | In particular this flag changes the behavior of operator* to a coeff wise product.
* * updated the assignement operator macro so that overloadsGravatar Gael Guennebaud2008-05-28
| | | | | | in MatrixBase work * removed product_selector and cleaned Product.h a bit * cleaned Assign.h a bit
* * change Flagged to take into account NestByValue onlyGravatar Gael Guennebaud2008-05-28
| | | | | * bugfix in Assign and cache friendly product (weird that worked before) * improved argument evaluation in Product
* * added _*coeffRef members in NestedByValueGravatar Gael Guennebaud2008-05-28
| | | | | | * added ConjugateReturnType and AdjointReturnType that are type-defined to Derived& and Transpose<Derived> if the scalar type is not complex: this avoids abusive copies in the cache friendly Product
