9eff685428 add matrix conjugation and adjunction. 
compilation fixes in the numeric traits.

96524fc573 Split Row and Column into separate files. 
Introduce a notion of RowVector (typedef for Matriw with 1 row)
Make row() return a row vector instead of a "column vector"
Introduce operator[] to access elements of row/column vectors uniformly
Remove default arguments in operator(), these were for vectors, now use operator[] instead

6015698047 Michael was right, it's best to base the unrolling limit on the product Rows*Cols. 2007-10-01 06:30:20 +00:00

656919619f - add copyright line for Michael Olbrich 
- some meta unrolling improvements

2d823d8ef6 Generic loop unrolling with template metaprograms. It seems to be as fast as 
manually unrolling.
TODO: decide when to stop unrolling (speed vs. code size).
      maybe only unroll one loop for larger matixes.

1d3743d2c5 for dynamic size matrix (Rows|Cols)AtCompileTime is always EiDynamic and not 
"(Rows|Cols)AtCompileTime - 1" which would be EiDynamic - 1 == -2

4241dddee9 temporarily remove division unit-tests. they caused div-by-zero's , reported by Michael Olbrich. 
The solution will consist in adding a real Traits system.

023773beaa Fix super-nasty bug in the declaration of the storage array of fixed-size matrices. 
Also some simplifications.

7d41ad9d90 Get rid of a nasty const_cast by introducing a MatrixConstRef class. 
Remove the __restrict__'s for now.

ee63e15e2c make matrix multiplication do immediate evaluation; add lazyMul() for the old behaviour 
some reorganization, especially in MatrixStorage
start playing with loop unrolling, always_inline, and __restrict__

835e0c9f67 Found a way to have eval() be a member function of class EiObject, instead of a global function.

28c44a95c2 Finish prefixing everything with "Ei" 2007-09-27 19:54:04 +00:00
Benoit Jacob
5160e9d029 Half-way commit prefixing object names. I am forced to commit now 
because I renamed a file once with a wrong filename and svn refuses to
let me rename it again, tells me i should propagate first.
 2007-09-27 19:38:40 +00:00
Benoit Jacob
4e299afb1f don't enclose eigen in a namespace. prefixing is the way to go. 
For example Qt uses a prefix and no namespace (except for a few things)

d99d9407df add operators *= and /= 2007-09-27 19:20:06 +00:00
Benoit Jacob
628b1a8f6d implement scalar operators separately for each type using a macro. 
This is required e.g. to allow "2 * m" with m a matrix of doubles.

8a024825d2 fix bugs caused by default copy constructors being called. valgrind, 
you saved my life.

a2dd9dd6f9 Give the axe to the aliasing system. 
Improve the evaluation system instead.

55227b1f63 Deep refactoring. 
1) Kill MatrixXpr class, instead let all class inherit a common EigenBase class
2) Kill MatrixBase/Matrix/Vector classes, instead introduce a single Matrix class,
a MatrixStorage class, and typedefs to emulate vectors
3) Huge code cleanup, remove large preprocessor macros, sloccount drop to ~750
down from 1100.
4) Introduce compile-time-known sizes

1af61c6ff0 reorganize header files, split MatrixBase into smaller files. 
expose only a few meta-headers to the user, the rest moves to a internal/ subdirectory

fe9b6b8f17 remove the MatrixConstXpr and MatrixConstRef classes. 
Now the user doesn't need anymore to call .xpr() and can simply do:
matrix.row(i) += matrix.row(j)

Also remove the obsolete MatrixXpr::hasDynamicSize() method (thanks to
Michael Olbrich for reporting this).
