* Added initial NEON support, most tests pass however we had to use some ↵Gravatar Konstantinos Margaritis2010-03-03
| | | | | | | | hackish workarounds as gcc on ARM (both CodeSourcery 4.4.1 used and experimental 4.5) fail to ensure proper alignment with __attribute__((aligned(16))). This has to be fixed upstream to remove the workarounds.

| | | | | | | | This was implementing deep changes that after discussion on the mailing list seem to need further discussion/thinking.
* | Added a missing inline hints.Gravatar Hauke Heibel2010-03-03
| | | | | | | | Removed a useless Nested temporary.
* | Adapted the comment and removed it from the public dox.Gravatar Hauke Heibel2010-03-03

* | Added a comment to prevent placing an EIGEN_STRONG_INLINE where it makes no ↵Gravatar Hauke Heibel2010-03-02

* a matrix (or array) does not always have the LinearAccessBit!Gravatar Gael Guennebaud2010-03-02
| | | | => fixes in outerStride and matrix flags
* selfadjoint: do not reference the imaginary part of the diagonalGravatar Gael Guennebaud2010-03-02
|
* Fixes a compilation issue for MSVC.Gravatar Hauke Heibel2010-03-01
|
* remove the hack to make the static assertion on types actually show up.Gravatar Benoit Jacob2010-02-28
| | | | indeed, now that we use the meta selector for transposing as needed, the static asserts work very well.
* forgot defined(...)Gravatar Benoit Jacob2010-02-28
|
* on 64-bit systems, glibc's malloc returns 16-byte aligned ptrs, and we now ↵Gravatar Benoit Jacob2010-02-28
| | | | take advantage of that.
* * fix ei_handmade_aligned_realloc (was calling realloc on wrong ptr)Gravatar Benoit Jacob2010-02-28
| | | | | * add missing std:: (at least for QNX compatibility) * add big comments to "structure" the file
* Added a generic reallocation implementation based on ei_aligned_malloc/_free.Gravatar Hauke Heibel2010-02-28
| | | | | | Rewrote ei_handmade_aligned_realloc such that it is now using std::realloc. Reorganized functions in Memory.h for better readability. Add missing <cerrno> include to Core (it's now required in Memory.h).
* Hide some internal stuff from the docs.Gravatar Hauke Heibel2010-02-28

* dot: handle the rowvector.dot(colvector) case where one needs to transpose.Gravatar Benoit Jacob2010-02-27
|
* Remove the dot product's separate implementation and use cwiseProduct.sum ↵Gravatar Benoit Jacob2010-02-27
| | | | | | instead. Also take special care to get nicely working static assertions.

* | * Implement the ByOuterInner accessorsGravatar Benoit Jacob2010-02-25
| | | | | | | | | | | | | | | | * use them (big simplification in Assign.h) * axe (Inner|Outer)StrideAtCompileTime that were just introduced * ei_int_if_dynamic now asserts that the size is the expected one: adapt to that in Block.h * add rowStride() / colStride() in DenseBase * implement innerStride() / outerStride() everywhere needed
| * ComplexSchur: compute shift more stably, introduce exceptional shifts.Gravatar Jitse Niesen2010-02-25
| | | | | | | | | | Both the new computation of the eigenvalues of a 2x2 block and the exceptional shifts are taken from EISPACK routine COMQR.

| * detect and implement inplace permutationsGravatar Gael Guennebaud2010-02-25

| | | | | | | | * proper capitalization: SSE, AltiVec
| * oops, fix typoGravatar Thomas Capricelli2010-02-25
| |
| * provide a static method to describe which SIMD instructions are usedGravatar Thomas Capricelli2010-02-24
| |
| * Provide "eigen" defines to decide which instruction set is usedGravatar Thomas Capricelli2010-02-24
| | | | | | | | | | | | (sse3, ssse3 and sse4), independantly from the compiler. Only those defines should be used in other places, and the user can rely on those to know which sets are used.
| * add reconstructedMatrix() to LLT, and LUsGravatar Gael Guennebaud2010-02-24
| | | | | | | | | | => they show that some improvements have still to be done for permutations, tr*tr, trapezoidal matrices

| | | | | | | | | | | | not even with huge numbers of repetitions. Finally the createRandomMatrixOfRank() function is renamed to createRandomPIMatrixOfRank, where PI stands for 'partial isometry', that is, a matrix whose singular values are 0 or 1.
