* Add Inverse_NEON.hGravatar Stephen Zheng2020-09-04
| | | | | | | | | | | Implemented fast size-4 matrix inverse (mimicking Inverse_SSE.h) using NEON intrinsics. ``` Benchmark Time CPU Time Old Time New CPU Old CPU New -------------------------------------------------------------------------------------------------------- BM_float -0.1285 -0.1275 568 495 572 499 BM_double -0.2265 -0.2254 638 494 641 496 ```

| | | | | | | | compilation error is raised, if this compile-switch is defined. The documentation references to the corresponding pages from Eigen3.2 now. Also, the Eigen2 testsuite has been removed.

* Get rid of include directives inside namespace blocks (bug #339).Gravatar Jitse Niesen2012-04-15

* add a "using MKL" documentation page, add a minimal documentation of PARDISO ↵Gravatar Gael Guennebaud2011-12-09
| | | | wrapper classes, refine a bit the EIGEN_USE_* logic
* - split and rename defined tokens to enable the use of BLAS/Lapack/VML/etcGravatar Gael Guennebaud2011-12-09
| | | | - include MKL headers outside the Eigen namespace.
* 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.
* shut up stupid ICC warningsGravatar Benoit Jacob2011-02-22

* eigen2: pass lu testGravatar Benoit Jacob2011-01-25
|
* only include SSE path if SSE enabledGravatar Benoit Jacob2009-12-14
|
* add SSE path for Matrix4f inverse, taken from Intel except that we do a kosherGravatar Benoit Jacob2009-12-14
| | | | | | division instead of RCPPS-followed-by-Newton-Raphson. The rationale for that is that elsewhere in Eigen we dont allow ourselves this approximation (which throws 2 bits of mantissa), so there's no reason we should allow it here.
* added comments to help vim understand the header files are c++.Gravatar Mark Borgerding2009-12-01
|
* introduce ei_xxx_return_value and ei_xxx_impl for xxx in solve,kernel,implGravatar Benoit Jacob2009-11-03
| | | | put them in a new internal 'misc' directory
* big huge changes, so i dont remember everything.Gravatar Benoit Jacob2009-10-28
| | | | | | | | | | * renaming, e.g. LU ---> FullPivLU * split tests framework: more robust, e.g. dont generate empty tests if a number is skipped * make all remaining tests use that splitting, as needed. * Fix 4x4 inversion (see stable branch) * Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices. * CMakeLists: more robust regexp to parse the version number * misc fixes in unit tests
* add partial-pivoting LU decompositionGravatar Benoit Jacob2009-05-13
| | | | | | the name 'PartialLU' is not meant to be definitive! make inverse() and determinant() use it, so it's *almost* considered well tested.
* Patch by Kenneth Riddile: disable MSVC warnings, reenable them outsideGravatar Benoit Jacob2008-12-18
| | | | of Eigen, and add a MSVC-friendly path in StaticAssert.
* Complete LU documentationGravatar Benoit Jacob2008-08-11
|
* * LU decomposition, supporting all rectangular matrices, with fullGravatar Benoit Jacob2008-08-04
| | | | | | | | | | pivoting for better numerical stability. For now the only application is determinant. * New determinant unit-test. * Disable most of Swap.h for now as it makes LU fail (mysterious). Anyway Swap needs a big overhaul as proposed on IRC. * Remnants of old class Inverse removed. * Some warnings fixed.
* Add .perpendicular() function in Geometry module (adapted from Eigen1)Gravatar Gael Guennebaud2008-07-22
| | | | | | Documentation: * add an overview for each module. * add an example for .all() and Cwise::operator<
* -fix certain #includesGravatar Benoit Jacob2008-05-12
| | | | -fix CMakeLists, public headers weren't getting installed
* - optimized determinant calculations for small matrices (size <= 4)Gravatar Benoit Jacob2008-04-14
| | | | | | | (only 30 muls for size 4) - rework the matrix inversion: now using cofactor technique for size<=3, so the ugly unrolling is only used for size 4 anymore, and even there I'm looking to get rid of it.
* * Start of the LU module, with matrix inversion already there andGravatar Benoit Jacob2008-04-14
fully optimized. * Even if LargeBit is set, only parallelize for large enough objects (controlled by EIGEN_PARALLELIZATION_TRESHOLD).
