e80f0b6c4e update doc of DiagonalCoeffs 2009-02-05 18:39:23 +00:00
Gael Guennebaud
910b387438 Add sub/super-diagonal expression (read/write) as a trivial extension of 
DiagonalCoeffs. The current API is simply:
  m.diagonal<1>() => 1st super diagonal
  m.diagonal<-2>() => the 2nd sub diagonal
I'll add a code snippet once we agree on this API.

93a089adc8 disable alignment altogether outside of the platforms which potentially have SSE or AltiVec 
This should remove most portability issues to other platforms where data alignment issues (including
overloading operator new and new[]) can be tricky, and where data alignment is not needed in the first place.

95db32fcdc setup the unsupported directory structure. 
The unsupported module documentation is automatically generated in:
  build/doc/unsupported/
with bidirectional cross references.
I leave a class Foo in AdolcForward module to illustrate the
cross-reference behavior. I will remove it in the next commit.

36c8a64923 add MatrixBase::stableNorm() avoiding over/under-flow 
using it in QR reduced the error of Keir test from 1e-12 to 1e-24 but
that's much more expensive !

9bc44094c5 add EIGEN_NO_AUTOMATIC_RESIZING 
if defined, already initialized matrices won't be automatically resized in assignments
uninitialized matrices may still be initialized

1b194193ef Big change in DiagonalMatrix and Geometry/Scaling: 
* previous DiagonalMatrix expression is now DiagonalMatrixWrapper
* DiagonalMatrix class is now for storage
* add the DiagonalMatrixBase class to factorize code of the
  two previous classes
* remove Scaling class (it is now a global function)
* add UniformScaling helper class
  (don't use it directly, use the Scaling function)
* add the Scaling global function to simplify the creation
  of scaling objects
There is still a lot to do, in particular about DiagonalProduct for which
the goal is to get rid of the "if()" in the coeff() function. At least
it is not worse than before ! Also need to uptade the tutorial and add more doc.

0f15a8d829 QR: add isInjective(), isSurjective(), 
mark isFullRank() deprecated,
    add solve() (mix of Keir's patch and LU::solve())

cf89d9371a LLT: makes the non positive definite test less strict, but we still need 
something better.

f6aa60bcf3 centralize those static asserts more upstream, reduces duplication and ensures they can't be bypassed (e.g. 
until now it was possible to bypass the static assert on sizes)

b05c5dd1be compute the rank on the fly rather than at the end, and stop early 
in the case of non-full rank (so big optimization in case the rank is low)

00d7f8e567 * solveTriangularInPlace(): take a const ref and const_cast it, to allow passing temporary xprs. 
* improvements, simplifications in LU::solve()
* remove remnant of old norm2()

414ee1db4b Optimization in LU::solve: when rows<=cols, no need to compute the L matrix 
Remove matrixL() and matrixU() methods: they were tricky, returning a Part,
and matrixL() was useless for non-square LU. Also they were untested. This is
the occasion to simplify the docs (class_LU.cpp) removing the most confusing part.
I think that it's better to let the user do his own cooking with Part's.
