797f63044a oops, forgot to add DenseDirectAccessBase 2010-04-16 14:46:55 -04:00

d9ee28851e fix ei_blas_traits directaccess check: in the case of vectors, having a nontrivial inner stride is OK. 2010-04-16 14:12:53 -04:00

04c663840b * add some 1x1 tests 
* temporarily disable tests that strangely fail, with a big FIXME

0ab431d7b8 * merge with mainline 
* adapt Eigenvalues module to the new rule that the RowMajorBit must have the proper value for vectors
* Fix RowMajorBit in ei_traits<ProductBase>
* Fix vectorizability logic in CoeffBasedProduct

ff6a46105d * Refactoring of the class hierarchy: introduction of DenseDirectAccessBase, removal of extra _Base/_Options template parameters. 
* Introduction of strides-at-compile-time so for example the optimized code really knows when it needs to evaluate to a temporary
* StorageKind / XprKind
* Quaternion::setFromTwoVectors: use JacobiSVD instead of SVD
* ComplexSchur: support the 1x1 case

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
Benoit Jacob
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
Benoit Jacob
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.
