* * 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.
* Respect MaxRowsAtCompileTime in HouseholderSequence::evalTo().Gravatar Jitse Niesen2010-05-25
| | | | | This fixes the failing test nomalloc_4. Also remove a print inserted for debugging in schur_real test.
* Update eigenvalues() and operatorNorm() methods in MatrixBase.Gravatar Jitse Niesen2010-05-24
| | | | | | | | * use SelfAdjointView instead of Eigen2's SelfAdjoint flag. * add tests and documentation. * allow eigenvalues() for non-selfadjoint matrices. * they no longer depend only on SelfAdjointEigenSolver, so move them to a separate file

* Change return type of matrixH() method to HouseholderSequence.Gravatar Jitse Niesen2010-05-24

| | | | | | methods go. Rationale: coeffRef() methods should only exist when we have DirectAccess. So a natural thing to do would have been to use enable_if, but since there are many methods it made more sense to do the "enable_if" for the whole group by introducing a new class. And that also that the benefit of not changing method prototypes.

| | | | | | | | | | | 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.
