As discussed on the list (too long to explain here).

e277586958 Complete rework of global math functions and NumTraits. 
* Now completely generic so all standard integer types (like char...) are supported.
** add unit test for that (integer_types).
* NumTraits does no longer inherit numeric_limits
* All math functions are now templated
* Better guard (static asserts) against using certain math functions on integer types.

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:

2f74801ca4 as discussed on list: default to align cols, reorganize parameters accordingly so that the default corresponds to 0 flag, 
and implement FullPrecision output (non-default).

76a3089a43 oops, don't set the precision to -1 !! 2009-08-13 09:56:53 -04:00
Benoit Jacob
1d80f561ad apply change discussed on the list : 
* new default precision "-1" means use the current stream precision
* otherwise, save and restore the stream precision

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?

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.

89f468671d * replace postfix ++ by prefix ++ wherever that makes sense in Eigen/ 
* fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated"
warning which I haven't looked much into

bfe86b8fc0 * add documentation of the cool (?) "print with format" feature 
* move the ioformat.cpp test to a documentation example
* rename IoFormat => IOFormat
 2008-08-23 19:41:00 +00:00

f729fc1d70 * Add the possibility to customize the output of matrices, e.g.: 
IoFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]");
   cout << mat.format(OctaveFmt);
  The first "4" is the precision.
  Documentation missing.
* Some compilation fixes

a9d319d44f * do the ActualPacketAccesBit change as discussed on list 
* add comment in Product.h about CanVectorizeInner
* fix typo in test/product.cpp

25ba9f377c * add bench/benchVecAdd.cpp by Gael, fix crash (ei_pload on non-aligned) 
* introduce packet(int), make use of it in linear vectorized paths
  --> completely fixes the slowdown noticed in benchVecAdd.
* generalize coeff(int) to linear-access xprs
* clarify the access flag bits
* rework api dox in Coeffs.h and util/Constants.h
* improve certain expressions's flags, allowing more vectorization
* fix bug in Block: start(int) and end(int) returned dyn*dyn size
* fix bug in Block: just because the Eval type has packet access
  doesn't imply the block xpr should have it too.

f279162ec4 * introducte recursive Flags system for the expressions 
-- currently 3 flags: RowMajor, Lazy and Large
 -- only RowMajor actually used for now
* many minor improvements

01572b9f54 big change: MatrixBase only takes one template parameter "Derived", the 
template parameter "Scalar" is removed. This is achieved by introducting a
template <typename Derived> struct Scalar to achieve a forward-declaration of
the Scalar typedefs.
