* Ensured that contractions that can be reduced to a matrix vector product ↵Gravatar Benoit Steiner2015-01-06
| | | | work correctly even when the input coefficients aren't aligned.
* Generalized the matrix vector product code.Gravatar Benoit Steiner2014-10-31
|
* Enable vectorization of gemv for PacketSize>4 through unaligned loads (still ↵Gravatar Gael Guennebaud2014-03-28

* Merged eigen/eigen into defaultGravatar Benoit Steiner2014-02-24

| * Implement bug #317: use a template function call to suppress unused variable ↵Gravatar Gael Guennebaud2014-02-24

* | Reverted the definition of the EIGEN_ALIGN to its former meaning (i.e. a ↵Gravatar Benoit Steiner2014-02-18
| | | | | | | | | | | | | | | | boolean) Created a new EIGEN_ALIGN_BYTES define to encode how the data should be aligned Fixed a few remaining alignment issues exposed when the Eigen code is compiled with avx enabled. Created a new EIGEN_ALIGN_DEFAULT define, which is set to the minimum alignment value required for the chosen instruction set. Use this value instead of EIGEN_ALIGN32 to preserve the existing alignment on SSE/Altivec/Neon.

|
* Fix out-of-range memory access in GEMV (the memory was not used for the ↵Gravatar Gael Guennebaud2012-08-30

* Intel(R) MKL support added.Gravatar karturov2011-12-05
| | | | | | | | | | * * * License disclaimer changed to BSD license for MKL_support.h * * * Pardiso support fixed, test added. blas/lapack tests fixed: Scalar parameter was added in Cholesky, product_matrix_vector_triangular remaned to triangular_matrix_vector_product. * * * PARDISO test was added physically.
* protect calls to min and max with parentheses to make Eigen compatible with ↵Gravatar Gael Guennebaud2011-07-21

* Initial fixes for bug #85.Gravatar Hauke Heibel2010-10-25
| | | | | | | Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const. Changed boolean type 'ret' member to 'value'. Changed 'ret' members refering to types to 'type'. Adapted all code occurences.
* bug #86 : use internal:: namespace instead of ei_ prefixGravatar Benoit Jacob2010-10-25
|
* fix warnings. The one in Reverse was potentially serious: coeff() methods ↵Gravatar Benoit Jacob2010-08-03
| | | | should return CoeffReturnType, not "Scalar", if the expression is potentially a Lvalue.
* sync with default branchGravatar Gael Guennebaud2010-07-22

* big addons:Gravatar Gael Guennebaud2009-03-05
| | | | | | | | | | | * add Homogeneous expression for vector and set of vectors (aka matrix) => the next step will be to overload operator* * add homogeneous normalization (again for vector and set of vectors) * add a Replicate expression (with uni-directional replication facilities) => for all of them I'll add examples once we agree on the API * fix gcc-4.4 warnings * rename reverse.cpp array_reverse.cpp
* * split CacheFriendlyProduct into multiple smaller filesGravatar Gael Guennebaud2009-02-21
* add an efficient selfadjoint * vector implementation (= blas symv) perf are inbetween MKL and GOTO => the interface is still missing (have to be rethougth)
