* big changes in Doxygen configuration; work around bug with doxygen parsing ofGravatar Benoit Jacob2008-06-02
| | | | | initialized enum values showing the last word the initializer instead of the actual enum value's name; add some more docs.
* - add MatrixBase::eigenvalues() convenience methodGravatar Benoit Jacob2008-06-02
| | | | | | - add MatrixBase::matrixNorm(); in the non-selfadjoint case, we reduce to the selfadjoint case by using the "C*-identity" a.k.a. norm of x = sqrt(norm of x * x.adjoint())
* 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
* - introduce Part and Extract classes, splitting and extending the formerGravatar Benoit Jacob2008-05-27
| | | | | | | | | | Triangular class - full meta-unrolling in Part - move inverseProduct() to MatrixBase - compilation fix in ProductWIP: introduce a meta-selector to only do direct access on types that support it. - phase out the old Product, remove the WIP_DIRTY stuff. - misc renaming and fixes
* * Give Konstantinos a copyright lineGravatar Benoit Jacob2008-05-12
| | | | | | | | * Fix compilation of Inverse.h with vectorisation * Introduce EIGEN_GNUC_AT_LEAST(x,y) macro doing future-proof (e.g. gcc v5.0) check * Only use ProductWIP if vectorisation is enabled * rename EIGEN_ALWAYS_INLINE -> EIGEN_INLINE with fall-back to inline keyword * some cleanup/indentation
* some cleaning in Cholesky and removed evil ei_sqrt of complexGravatar Gael Guennebaud2008-04-27

* Added Triangular expression to extract upper or lower (strictly or not)Gravatar Gael Guennebaud2008-04-26
| | | | | | | | | | | part of a matrix. Triangular also provide an optimised method for forward and backward substitution. Further optimizations regarding assignments and products might come later. Updated determinant() to take into account triangular matrices. Started the QR module with a QR decompostion algorithm. Help needed to build a QR algorithm (eigen solver) based on it.
* fix a bug in determinant of 4x4 matrices and a small type issue in InverseGravatar Gael Guennebaud2008-04-26

* give up on OpenMP... for nowGravatar Benoit Jacob2008-04-18

* - add _packetCoeff() to Inverse, allowing vectorization.Gravatar Benoit Jacob2008-04-16
| | | | | | | | | - let Inverse take template parameter MatrixType instead of ExpressionType, in order to reduce executable code size when taking inverses of xpr's. - introduce ei_corrected_matrix_flags : the flags template parameter to the Matrix class is only a suggestion. This is also useful in ei_eval.
* +5% optimization in 4x4 inverse:Gravatar Benoit Jacob2008-04-15
| | | | | -only evaluate block expressions for which that is beneficial -don't check for invertibility unless requested
* for 4x4 matrices implement the special algorithm that Markos proposed,Gravatar Benoit Jacob2008-04-15
| | | | falling back to the general algorithm in the bad case.
* - 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).
