3cc9e3f5bb Fixes a compilation issue for MSVC. 2010-03-01 19:56:24 +01:00

f1f3c30ddc remove the hack to make the static assertion on types actually show up. 
indeed, now that we use the meta selector for transposing as needed, the static asserts work very well.

9334ed4444 on 64-bit systems, glibc's malloc returns 16-byte aligned ptrs, and we now take advantage of that. 2010-02-28 10:10:53 -05:00

a480e7e60f * fix ei_handmade_aligned_realloc (was calling realloc on wrong ptr) 
* add missing std::  (at least for QNX compatibility)
* add big comments to "structure" the file

ff8c2149c1 Added a generic reallocation implementation based on ei_aligned_malloc/_free. 
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).

d9f6380499 Remove the dot product's separate implementation and use cwiseProduct.sum instead. 
Also take special care to get nicely working static  assertions.

32115bff1e * add VERIFY_IS_EQUAL, should compile faster and it's natural when no arithmetic is involved. 
* rename 'submatrices' test to 'block'
* add block-inside-of-block tests
* remove old cruft
* split diagonal() tests into separate file

769641bc58 * Implement the ByOuterInner accessors 
* 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

90e4a605ef ComplexSchur: compute shift more stably, introduce exceptional shifts. 
Both the new computation of  the eigenvalues of a 2x2 block and the
exceptional shifts are taken from EISPACK routine COMQR.

00bc535b66 provide a static method to describe which SIMD instructions are used 2010-02-24 21:52:08 +01:00
Thomas Capricelli
0f3d69b65e Provide "eigen" defines to decide which instruction set is used 
(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.

7c98c04412 add reconstructedMatrix() to LLT, and LUs

3d066f4bc7 LDLT: 
* fix bug thanks to Ben Goodrich: we were terminating at the wrong place, leaving some matrix coefficients with wrong values.
* don't use Higham's formula here: we're not trying to be rank-revealing.

d92df336ad Further LU test improvements. I'm not aware of any test failures anymore, 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.

7dc75380c1 * FullPivLU: replace "remaining==0" termination condition (from Golub) by a fuzzy compare 
(fixes lu test failures when testing solve())
* LU test: set appropriate threshold and limit the number of times that a specially tricky test
  is run. (fixes lu test failures when testing rank()).
* Tests: rename createRandomMatrixOfRank to createRandomProjectionOfRank
