3a14a13533 Split computation of real Schur form in EigenSolver to its own class. 
This is done with the minimal amount of work, so the result is very rough.

338ec0390f let the cast functor use the new ei_cast() 2010-03-30 14:51:47 -04:00

16e416b8d7 generalize the idea of the previous commit to all kinds of casts, see this forum thread: 
http://forum.kde.org/viewtopic.php?f=74&t=86914
this  is important to allow users to support custom types that don't have the needed conversion operators.

9e0d8697c7 add ei_cast_to_int, we are indeed somethings (e.g. in IO.h) casting scalars to int and the only way to allow users to extend that to their own scalar types that don't have int cast operators, was to allow them specialize ei_cast_to_int_impl. 2010-03-30 14:16:54 -04:00

8f99ae5ea4 move the computation of the number of significant digits to a templated helper struct, that can be specialized to custom types if needed. Should address this request:

307c428253 Move documentation of MatrixBase methods in MatrixFunctions to module page. 
I think that because MatrixFunctions is in unsupported/ and MatrixBase is
not, doxygen does not include the MatrixBase methods defined and documented
in the MatrixFunctions module with the other MatrixBase methods. This is a
kludge, but at least the documentation is not lost.

b81351cb07 nomalloc: minor cleanup 2010-03-08 21:30:06 -05:00
Adolfo Rodriguez Tsouroukdissian
5a36f4a8d1 Propagate all five matrix template parameters to members and temporaries of 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.
