b1f666d007 Fix Map-with-Stride and cover it by new unit tests. 2010-02-26 20:12:51 -05:00
Benoit Jacob
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 
=> they show that some improvements have still to be done
   for permutations, tr*tr, trapezoidal matrices

f7aa9873ca * fix LDLT's default ctor use 
* add a reconstructedMatrix() function to LDLT for debug purpose

60325b8330 actually, this is not even meant to be a termination criterion. so the proper fix is this. 2010-02-23 16:10:26 -05:00

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

51a4b929a1 implement an even lower level version of the gebp kernel for MSVC (it seems to be faster with gcc as well)

b73e22905d miserable half-working state, commiting to a fork just in case, just to perfect 
my day, my hard disk would die.
Will write a more detailed commit message once it's working.

37ca4200b2 Piotr's patch was missing many occurences of size_t. So, 
using std::size_t;
This is the only way that we can ensure QCC support in the long term without having to think about it everytime.
