  • 7ddc13b9fa use a more c++-ish way of preventing the compiler from generating default operator= when it's not wanted. Thanks to Christian Mayer for the tip. Benoit Jacob 2007-12-12 16:52:17 +00:00
  • fa8009c6b7 1) remove EIGEN_UNUSED, instead use non-named arguments. 2) use T instead of const T& when that makes more sense Thanks to Christian Mayer a.k.a Mekhzolan for the tips. Benoit Jacob 2007-12-11 15:25:43 +00:00
  • 0cbdaf6bb8 revert most of my previous commit. forcing the compiler to inline only increased its memory usage. Benoit Jacob 2007-12-11 14:57:42 +00:00
  • 936b0de9cc play with inlining to get better performance when the compiler is not asked to optimize Benoit Jacob 2007-12-11 13:14:14 +00:00
  • 8117c9aa83 oops, forgot to commit that change Benoit Jacob 2007-12-11 10:48:35 +00:00
  • 0a7086f1ec rename CopyHelper into OperatorEquals, get rid of the auxiliary _copy_helper() method, and make sure copies are always done in column-dominant order Benoit Jacob 2007-12-11 10:19:49 +00:00

  • 9d51572cbe rework the random numbers API Benoit Jacob 2007-12-11 10:02:48 +00:00
  • c58c892e25 had forgotten to 'svn add' that file... Benoit Jacob 2007-12-05 08:57:23 +00:00
  • 68eba600b1 big reorganisation of asserts, so that: 0) asserts are only done in the public API, except for a few ones explicitly named eigen_internal_assert. 1) internal asserts are disabled unless EIGEN_INTERNAL_DEBUGGING is defined. This limits the impact of debugging on performance. 2) no 'unused argument' warnings anymore when compiling with -DNDEBUG Benoit Jacob 2007-12-05 08:56:42 +00:00
  • b569216dc3 remove useless default argument values Benoit Jacob 2007-12-05 07:44:57 +00:00

  • 346c00f4c8 Rework the unit-tests to use lower precision, so as to eliminate false positives. Also some cleanup in the fuzzy compares. Benoit Jacob 2007-12-03 10:23:08 +00:00
  • 5abaaf9688 Test application now takes 'seed' and 'repeat' command-line args Benoit Jacob 2007-12-03 08:35:23 +00:00
  • e05f29191e Much more convenient, less over-engineered NumTraits. Done during this KDE-Edu weekend. Benoit Jacob 2007-12-02 18:32:59 +00:00
  • 2fdd067d9e add more unit-tests (covering transpose, conjugate, adjoint, dot product...) Benoit Jacob 2007-11-28 15:34:40 +00:00
  • 39f1776bde rename Object -> MatrixBase Benoit Jacob 2007-11-27 13:57:51 +00:00
  • 344623e872 Matrix(int) constructor is only for vectors. Benoit Jacob 2007-11-26 09:21:11 +00:00
  • a587346b47 Matrix(int,int) constructor no longer takes default arguments. Instead, introduce Matrix() and Matrix(int); however, dynamic dimensions are required to be specified in the constructor (we no longer default to 1) Benoit Jacob 2007-11-26 09:11:12 +00:00
  • 5309ef5b5e - improve and comment the "BasicStuff" test. - adjust behavior of Matrix(int,int) constructor - s/EI_/EIGEN_/ Benoit Jacob 2007-11-26 08:47:07 +00:00

  • d6f26dc8eb clarify the situation with EI_INHERIT_ASSIGNMENT_OPERATORS Benoit Jacob 2007-10-15 06:11:59 +00:00
  • 884a718b0a make shameless use of const_cast to reduce code redundancy. This means Eigen2 gives up enforcing constness. I really tried to enforce it, but it really was much hassle because our expression templates can be lvalues (not only rvalues) and so much code had to be written twice. Benoit Jacob 2007-10-15 05:56:21 +00:00
  • f355ef2df0 Merge WrapArray into FromArray. Less code. The downside is that we're using one more const_cast. But I think that anyway trying to maintain const strictness in Eigen2 is not worth the hassle. Benoit Jacob 2007-10-14 18:02:16 +00:00

  • 5f0af72abc mark more methods as const. also rename, Numeric.h->NumTraits.h Benoit Jacob 2007-10-13 20:53:30 +00:00
  • e445f5085a implement the first _real_ unit-tests, testing the results for correctness instead of just checking compilation. Benoit Jacob 2007-10-13 16:56:24 +00:00
  • 31061557a5 add unary operator-(), computing the opposite. Benoit Jacob 2007-10-13 14:38:51 +00:00

  • e116aba444 adapt to coding style used elsewhere in eigen2 Benoit Jacob 2007-10-01 04:57:51 +00:00
  • 2d823d8ef6 Generic loop unrolling with template metaprograms. It seems to be as fast as manually unrolling. TODO: decide when to stop unrolling (speed vs. code size). maybe only unroll one loop for larger matixes. Michael Olbrich 2007-09-30 20:38:09 +00:00
  • 1d3743d2c5 for dynamic size matrix (Rows|Cols)AtCompileTime is always EiDynamic and not "(Rows|Cols)AtCompileTime - 1" which would be EiDynamic - 1 == -2 Michael Olbrich 2007-09-30 20:23:24 +00:00
  • 4241dddee9 temporarily remove division unit-tests. they caused div-by-zero's , reported by Michael Olbrich. The solution will consist in adding a real Traits system. Benoit Jacob 2007-09-30 16:45:40 +00:00

  • 28c44a95c2 Finish prefixing everything with "Ei" Benoit Jacob 2007-09-27 19:54:04 +00:00
  • 5160e9d029 Half-way commit prefixing object names. I am forced to commit now because I renamed a file once with a wrong filename and svn refuses to let me rename it again, tells me i should propagate first. Benoit Jacob 2007-09-27 19:38:40 +00:00
  • 4e299afb1f don't enclose eigen in a namespace. prefixing is the way to go. For example Qt uses a prefix and no namespace (except for a few things) Benoit Jacob 2007-09-27 19:24:57 +00:00
  • d99d9407df add operators *= and /= Benoit Jacob 2007-09-27 19:20:06 +00:00
  • 628b1a8f6d implement scalar operators separately for each type using a macro. This is required e.g. to allow "2 * m" with m a matrix of doubles. Benoit Jacob 2007-09-27 07:42:12 +00:00
  • 8a024825d2 fix bugs caused by default copy constructors being called. valgrind, you saved my life. Benoit Jacob 2007-09-26 14:06:32 +00:00
  • a2dd9dd6f9 Give the axe to the aliasing system. Improve the evaluation system instead. Benoit Jacob 2007-09-26 14:06:26 +00:00
  • 55227b1f63 Deep refactoring. 1) Kill MatrixXpr class, instead let all class inherit a common EigenBase class 2) Kill MatrixBase/Matrix/Vector classes, instead introduce a single Matrix class, a MatrixStorage class, and typedefs to emulate vectors 3) Huge code cleanup, remove large preprocessor macros, sloccount drop to ~750 down from 1100. 4) Introduce compile-time-known sizes Benoit Jacob 2007-09-26 14:06:14 +00:00
  • 1af61c6ff0 reorganize header files, split MatrixBase into smaller files. expose only a few meta-headers to the user, the rest moves to a internal/ subdirectory Benoit Jacob 2007-09-09 09:41:15 +00:00
