0dfb73d46a Fix LDLT with semi-definite complex matrices: owing to round-off errors, the diagonal was not real. Also exploit the fact that the diagonal is real in the rest of LDLT 2014-07-08 10:04:27 +02:00

ac69d8769f Remove early termination in LDLT: the zero on the diagonal of the input matrix does not mean the matrix is not full rank. Typical examples are matrices coming from LS with linear equality constraints. 2014-02-26 10:12:27 +01:00

7bc8e3ac09 Initial fixes for bug #85. 
Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const.
Changed boolean type 'ret' member to 'value'.
Changed 'ret' members refering to types to 'type'.
Adapted all code occurences.

28dde19e40 - Added problem size constructor to decompositions that did not have one. It 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.
