Benoit Jacob	c22d10f94c	LU class: ... * add image() and computeImage() methods, with unit test * fix a mistake in the definition of KernelResultType * fix and improve comments	2008-12-17 16:47:55 +00:00

Benoit Jacob	46fe7a3d9e	if EIGEN_NICE_RANDOM is defined, the random functions will return numbers with ... few bits left of the comma and for floating-point types will never return zero. This replaces the custom functions in test/main.h, so one does not anymore need to think about that when writing tests.	2008-09-01 17:31:21 +00:00
Gael Guennebaud	2120fed849	* bug fixes in: Dot, generalized eigen problem, singular matrix detetection in Cholesky ... * fix all numerical instabilies in the unit tests, now all tests can be run 2000 times with almost zero failures.	2008-08-23 15:14:20 +00:00
Gael Guennebaud	f0394edfa7	* bugfix in SolveTriangular found by Timothy Hunter (did not compiled for very small fixed size matrices) ... * bugfix in Dot unroller * added special random generator for the unit tests and reduced the tolerance threshold by an order of magnitude this fixes issues with sum.cpp but other tests still failed sometimes, this have to be carefully checked...	2008-08-22 17:48:36 +00:00
Benoit Jacob	d6e88f8155	* add LU unit-test. Seems like we have very good numerical stability! ... * some cleanup, and grant me a copyright line on the determinant test.	2008-08-09 19:26:14 +00:00
