a4487ef198 add snippet for sub/super diagonal
fix a few doc issues

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.

44a527dfa5 * classify and sort the doxygen "related pages"
by tweaking the filename and adding 2 categories:
   Troubleshooting and Advanced
* use the EXCLUDE_SYMBOLS to clean the class list
  (insteaded of a homemade bash script)
* remove the broken "exemple list"
* re-structure the unsupported directory as mentionned in the ML and
  integrate the doc as follow:
  - snippets of the unsupported directory are directly imported from the
    main snippets/CMakefile.txt (no need to duplicate code)
  - add a top level "Unsupported modules" group
  - unsupported modules have to defined their own sub group and nest it
    using \ingroup Unsupported_modules
  - then a pair of //@{ //@} will put everything in the submodule
  - this is just a proposal !

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.

eb7dcbbfce EIGEN_MAKE_ALIGNED_OPERATOR_NEW didn't actually need to get the class
name as parameter
2009-01-08 15:37:13 +00:00

1d52bd4cad the big memory changes. the most important changes are:
ei_aligned_malloc now really behaves like a malloc
 (untyped, doesn't call ctor)
ei_aligned_new is the typed variant calling ctor
EIGEN_MAKE_ALIGNED_OPERATOR_NEW now takes the class name as parameter
2009-01-08 15:20:21 +00:00

1c29d70312 * introduce macros to replace inheritance for operator new overloading
(former solution still available and tested)
  This plays much better with classes that already have base classes --
  don't force the user to mess with multiple inheritance, which gave
  much trouble with MSVC.
* Expand the unaligned assert dox page
* Minor fixes in the lazy evaluation dox page
2009-01-06 03:16:50 +00:00

9e00d94543 * the Upper->UpperTriangular change

fabaa6915b * fix in IO.h, a useless copy was made because of assignment from
Derived to MatrixBase.
* the optimization of eval() for Matrix now consists in a partial
  specialization of ei_eval, which returns a reference type for Matrix.
  No overriding of eval() in Matrix anymore. Consequence: careful,
  ei_eval is no longer guaranteed to give a plain matrix type!
  For that, use ei_plain_matrix_type, or the PlainMatrixType typedef.
* so lots of changes to adapt to that everywhere. Hope this doesn't
  break (too much) MSVC compilation.
* add code examples for the new image() stuff.
* lower a bit the precision for floats in the unit tests as
  we were already doing some workarounds in inverse.cpp and we got some
  failed tests.

8ea8b481de As discussed on ML:
* remove the automatic resizing feature of operator =
 * add function Matrix::set() to be used when the previous
   behavior is wanted
 * the default constructor of dynamic-size matrices now
   creates a "null" matrix (data=0, rows = cols = 0)
   instead of a 1x1 matrix
 * fix UnixX typos ;)

e747b338ee Started the third chapter of the tutorial on linear solvers.
It is only a first draft and I think it should be reorganized a bit in 2 parts:
1 - a compact table summarizing the main API and its use
    (this is what would expect an "expert" user)
2 - a discussion about the various algorithm in Eigen to guide the newbies in linear algebra
Currently I mixed the discussion with the API, but it is still better than nothing !

765219aa51 Big API change in Cholesky module:
* rename Cholesky to LLT
 * rename CholeskyWithoutSquareRoot to LDLT
 * rename MatrixBase::cholesky() to llt()
 * rename MatrixBase::choleskyNoSqrt() to ldlt()
 * make {LLT,LDLT}::solve() API consistent with other modules

Note that we are going to keep a source compatibility untill the next beta release.
E.g., the "old" Cholesky* classes, etc are still available for some time.
To be clear, Eigen beta2 should be (hopefully) source compatible with beta1,
and so beta2 will contain all the deprecated API of beta1. Those features marked
as deprecated will be removed in beta3 (or in the final 2.0 if there is no beta 3 !).

Also includes various updated in sparse Cholesky.

236b7a545d update Transform::inverse() to take an optional argument stating whether the transformation is:
NonAffine, Affine (default), contains NoShear, contains NoScaling
that allows significant speed improvements. If you like it, this concept could be applied to
Transform::extractRotation (or to a more advanced decomposition function) and to Hyperplane::transformed()
and maybe to some other places... e.g., I think a Transform::normalMatrix() function would not harm and
warn user that the transformation of normals is not that trivial (I saw this mistake much too often)

that it's super important to have fully compilable short programs (even
with compile instructions for the first one) not just small snippets, at
least at the beginning. Let's start with examples of compilable programs.

* rename matrixNorm() to operatorNorm(). There are many matrix norms
  (the L2 is another one) but only one is called the operator norm.

  and complex doesn't use the vectorized path anyway.
* fix bug in Block: a 3x1 block in a 4x4 matrix (all fixed-size)
  should not be vectorizable, since in fixed-size we are assuming
  the size to be a multiple of packet size. (Or would you prefer
  Vector3d to be flagged "packetaccess" even though no packet access
  is possible on vectors of that type?)
* rename:
  isOrtho for vectors ---> isOrthogonal
  isOrtho for matrices ---> isUnitary
* add normalize()
* reimplement normalized with quotient1 functor

8de4d92b70 - get the doc of the enums in MatrixBase right
- get the doc of the flags in Constants right
- finally give up with SEPARATE_MEMBER_PAGES: it triggers too big
  Doxygen bugs, and produces too many small pages. So we have one
  huge page for MatrixBase at currently 300kb and going up, so the
  solution especially for users with low bandwidth will be to provide
  an archive of the html documentation.

aebecae510 * find the proper way of nesting the expression in Flagged:
finally that's more subtle than just using ei_nested, because when
  flagging with NestByValueBit we want to store the expression by value

* rename temporary() ----> nestByValue()
* move the old Product.h to disabled/, replace by what was ProductWIP.h
* tweak -O and -g flags for tests and examples

c9b0dcd733 look at that subtle difference in Product.h...
the cacheOptimal is only good for large enough matrices.
When taking a block in a fixed-size (hence small) matrix,
the SizeAtCompileTime is Dynamic hence that's not a good
indicator. This example shows that the good indicator is
MaxSizeAtCompileTime.

* Remove findBiggestCoeff() as it's now almost redundant.
* Improve echelon.cpp: inner for loop replaced by xprs.
* remove useless "(*this)." here and there. I think they were

(the global funcs in MathFunctions.h and Fuzzy.h don't count as internal).
* Mainpage.dox. Add a few prospective Eigen users; change the recommended
  -finline-limit from 10000 to 1000. The reason is: it could be harmful to have
  a too big value here, couldn't it? (e.g. exceedingly large executables, cache
  misses). Looking at gcc, a value of 900 would exactly mean "determine the inlining
  of all functions as if they were marked with 'inline' keyword". So a value of
  1000 seems a reasonable round number. In the benchmark that motivated this
  (TestEigenSolvers) a value of 400 is enough on my system.

- apidoc improvements, reorganization of the \name's

  No support for xpr on the right side for the moment.

After huge thread on eigen mailing list, it appears that i'm the
only one in favor of prefix Ei. Everybody else prefers namespace
Eigen like we did in Eigen 1. So, revert.

Also add a macro USING_EIGEN_DATA_TYPES that application programmers
can use to automatically do "using"on the Matrix class and its
matrix/vector typedefs:
using Eigen::Matrix;
using Eigen::Matrix2d;
using Eigen::Vector2d;
... (the list of typedefs is really long).

thanks to the suffixes, the Vector typedefs aren't really polluting.
