* email changeGravatar Gael Guennebaud2010-06-24

* rename:Gravatar Benoit Jacob2010-06-14
| | | | | | EIGEN_SIZE_MIN ---> EIGEN_SIZE_MIN_PREFER_DYNAMIC EIGEN_MAXSIZE_MIN ---> EIGEN_SIZE_MIN_PREFER_FIXED and make sure to use the latter in products xprs to determine the inner size.

* | change the value of Dynamic to -1, since the index type is now configurable.Gravatar Benoit Jacob2010-06-11
| | | | | | | | remove EIGEN_ENUM_MIN/MAX, implement new macros instead

| * * add Transpositions to PermutationMatrix conversionGravatar Gael Guennebaud2010-06-08
| | | | | | | | * make PartialPivLu uses the Transpositions class
| * * remove ei_index, and let ei_traits propagate the index typesGravatar Gael Guennebaud2010-06-03
| | | | | | | | * add an Index type template parapeter to sparse objects
| * improve aliasing detection for inverse and add unit testGravatar Gael Guennebaud2010-06-02

| * Add cast to aliasing check.Gravatar Jitse Niesen2010-06-01
| | | | | | | | | | Otherwise, one of the geo tests fails to compile. Now there are some compiler warnings about aliasing and type-punned pointers that I don't understand.

* * Make ReturnByValue have the EvalBeforeAssigningBit and explicitlyGravatar Benoit Jacob2010-05-30
| | | | | | enforce this mechanism (otherwise ReturnByValue bypasses it). (use .noalias() to get the old behavior.) * Remove a hack in Inverse, futile optimization for 2x2 expressions.
* Complete rework of global math functions and NumTraits.Gravatar Benoit Jacob2010-04-28
| | | | | | | | * Now completely generic so all standard integer types (like char...) are supported. ** add unit test for that (integer_types). * NumTraits does no longer inherit numeric_limits * All math functions are now templated * Better guard (static asserts) against using certain math functions on integer types.
* remove MinorGravatar Benoit Jacob2010-04-22
| | | | adapt 3x3 and 4x4 (non-SSE) inverse paths
* * implement the corner() API change: new methods topLeftCorner() etcGravatar Benoit Jacob2010-04-22
| | | | | | | | * get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway * add topRows(), leftCols(), bottomRows(), rightCols() * add corners unit-test covering all of that * adapt docs, expand "porting from eigen 2 to 3" * adapt Eigen2Support
* - Added problem size constructor to decompositions that did not have one. It ↵Gravatar Adolfo Rodriguez Tsouroukdissian2010-04-21
| | | | | | | | | | | preallocates member data structures. - Updated unit tests to check above constructor. - In the compute() method of decompositions: Made temporary matrices/vectors class members to avoid heap allocations during compute() (when dynamic matrices are used, of course). These changes can speed up decomposition computation time when a solver instance is used to solve multiple same-sized problems. An added benefit is that the compute() method can now be invoked in contexts were heap allocations are forbidden, such as in real-time control loops. CAVEAT: Not all of the decompositions in the Eigenvalues module have a heap-allocation-free compute() method. A future patch may address this issue, but some required API changes need to be incorporated first.

* Propagate all five matrix template parameters to members and temporaries of ↵Gravatar Adolfo Rodriguez Tsouroukdissian2010-03-08
| | | | | | | decomposition classes. One particular advantage of this is that decomposing matrices with max sizes known at compile time will not allocate. NOTE: The ComplexEigenSolver class currently _does_ allocate (line 135 of Eigenvalues/ComplexEigenSolver.h), but the reason appears to be in the implementation of matrix-matrix products, and not in the decomposition itself. The nomalloc unit test has been extended to verify that decompositions do not allocate when max sizes are specified. There are currently two workarounds to prevent the test from failing (see comments in test/nomalloc.cpp), both of which are related to matrix products that allocate on the stack.
