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

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

67ce07ea83 matrix_function test: replace expm(A).inverse() by expm(-A) 
The latter is more stable. This fixes one of the issues with the test.
Also, make typedef's in MatrixFunctionReturnValue public; this is
necessary to get the test to compile.
