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

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.

b18f737aa1 Test matrix functions with matrices with clustered imaginary eivals. 
The idea is that these test MatrixFunction::swapEntriesInSchur(),
which is not covered by existing tests. This did not work out as
expected, but nevertheless it is a good test so I left it in.

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.
