* Return matrices by constant reference where possible.Gravatar Jitse Niesen2010-05-24
| | | | | | | This changes the return type of: * eigenvectors() and eigenvalues() in ComplexEigenSolver * eigenvalues() in EigenSolver * eigenvectors() and eigenvalues() in SelfAdjointEigenSolver
* Replace local variables by member variables in compute() methods.Gravatar Jitse Niesen2010-05-24
| | | | | | | This is to avoid dynamic memory allocations in the compute() methods of ComplexEigenSolver, EigenSolver, and SelfAdjointEigenSolver where possible. As a result, Tridiagonalization::decomposeInPlace() is no longer used. Biggest remaining issue is the allocation in HouseholderSequence::evalTo().
* - 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.
