Benoit Jacob	5a18f7545d	this is essentially backporting all the changes made in the Sparse module up to KDE SVN revision r945600, aka changeset: ... df9dfa145547529bf71afd4c6e8f3af947acaad0 This is what is needed to make Step (in KDE/kdeedu) build. The rest of Eigen (outside of Sparse) is unaffected except for a few trivial changes that were needed. calling this 2.0.3, will tag if no problem.	2009-06-04 18:02:20 +02:00
Gael Guennebaud	e7c48fac9b	sparse module: makes -= and += operator working ... Question 1: why are *=scalar and /=scalar working right away ? Same weirdness in DynamicSparseMatrix where operators += and -= work wihout having to redefine them ???	2009-01-23 13:59:32 +00:00
Gael Guennebaud	6a722602e6	fix a few remaining warnings ... and fix commainitializer unit test with MSVC	2009-01-23 12:26:32 +00:00
Gael Guennebaud	d3dcb04f2d	* fix compilation with gcc 3.4 ... * add an option to disable Qt testing	2009-01-23 09:50:16 +00:00
Gael Guennebaud	52cf07d266	sparse module: ... * add row(i), col(i) functions * add prune() function to remove small coefficients	2009-01-21 18:46:04 +00:00
Gael Guennebaud	178858f1bd	add a flexible sparse matrix class designed for fast matrix assembly	2009-01-19 15:20:45 +00:00
Gael Guennebaud	ccdcebcf03	Sparse module: add support for sparse selfadjoint * dense	2009-01-15 18:52:14 +00:00
Gael Guennebaud	9a4b7998cf	Sparse module: add row/col methods to the iterators	2009-01-15 14:16:41 +00:00
Gael Guennebaud	87241089e1	Sparse module: bugfix in SparseMatrix::resize(), now the indices are ... correctly initialized to 0.	2009-01-15 13:30:50 +00:00
Gael Guennebaud	2d53466fa9	Sparse module: ... * improved performance of mat*=scalar * bug fix in cwise*	2009-01-14 21:27:54 +00:00
Gael Guennebaud	0b606dcccd	Add support for sparse * dense and dense * sparse matrix/vector products	2009-01-14 17:41:55 +00:00
Gael Guennebaud	c4c70669d1	Big rewrite in the Sparse module: SparseMatrixBase no longer inherits MatrixBase. ... That means a lot of features which were available for sparse matrices via the dense (and super slow) implemention are no longer available. All features which make sense for sparse matrices (aka can be implemented efficiently) will be implemented soon, but don't expect to see an API as rich as for the dense path. Other changes: * no block(), row(), col() anymore. * instead use .innerVector() to get a col or row vector of a matrix. * .segment(), start(), end() will be back soon, not sure for block() * faster cwise product	2009-01-14 14:24:10 +00:00
Gael Guennebaud	5015e48361	Sparse module: add a more flexible SparseMatrix::fillrand() function ... which allows to fill a matrix with random inner coordinates (makes sense only when a very few coeffs are inserted per col/row)	2008-12-11 18:26:24 +00:00
Gael Guennebaud	86ccd99d8d	Several improvements in sparse module: ... * add a LDL^T factorization with solver using code from T. Davis's LDL library (LPGL2.1+) * various bug fixes in trianfular solver, matrix product, etc. * improve cmake files for the supported libraries * split the sparse unit test * etc.	2008-11-05 13:47:55 +00:00
