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

2110cca431 actually honor EIGEN_STACK_ALLOCATION. 
Can set it to 0 to disable stack alloc which guarantees that bad alloc throws exceptions if they are enabled.

38b83b4157 * throw bad_alloc if exceptions are enabled, after patch by Kenneth Riddile 
* disable vectorization on MSVC 2005, as it doesn't have all the required intrinsics. require 2008.

50105c3ed6 Hopefully fix compilation of SSE Packetmath with MSVC. 
The reason why we didn't realize until now that it didn't compile at all
with MSVC is that before today with MSVC the SSE2 detection didn't work.

0a220721d1 Finally work around enough of MSVC preprocessor dumbness so that it actually detects SSE2 2008-12-15 21:20:40 +00:00

1ad751b991 only enable the "unaligned array" assert if vectorization is enabled. 
if vectorization is disabled, WithAlignedOperatorNew is empty!

763f0a2434 use ei_aligned_malloc and ei_aligned_free also in WithAlignedOperatorNew, so this too should now work with MSVC. 2008-12-15 17:55:11 +00:00

5015e48361 Sparse module: add a more flexible SparseMatrix::fillrand() function 
which allows to fill a matrix with random inner coordinates (makes sense
only when a very few coeffs are inserted per col/row)

beabf008b0 bugfix in DiagonalProduct: a "DiagonalProduct<SomeXpr>" expression 
is now evaluated as a "DiagonalProduct<Matrix<SomeXpr::Eval> >".
Note that currently this only happens in DiagonalProduct.

cb409914e0 * call it beta2 
* improvements in Matrix documentation
* document copyCoeff and copyPacket even if it's hidden from doxygen
 2008-12-07 23:23:36 +00:00
Benoit Jacob
069ecbb4ab * complete the change norm2->squaredNorm in PartialRedux 
* somehow the NICE_RANDOM stuff wasn't being used anymore and
  tests were sometimes failing again. Fixed by #including Eigen/Array
  instead of cherry-picking just Random.h.
* little fixes in the unaligned assert page
 2008-12-07 21:40:53 +00:00

09fd69d734 * add Transform explicit constructors taking translation/scaling/rotation 
* add Transform::operator= taking rotation.
  An old remnant was left commented out. Why was it disabled?
* slight optimization in operator= taking translation
* slight optimization (perhaps) in the new memory assertion

7e8ee5b527 hide internal stuff from doxygen by using #ifndef EIGEN_PARSED_BY_DOXYGEN. 
Sadly, \internal didn't hide internal stuff, it only hides the documentation!

faf942a947 Add a generic matrix to Euler-angles function. 
Perhaps the prototype of this function could be improved,

2ff7961c10 split off the lazy evaluation part from the quickstartguide; actually by mistake i had 
already committed part of that change so i commit the rest even if it's not much, so
building docs from trunk works again.

c1e2156d8a * Much better, consistent error msgs when mixing different scalar types: 
- in matrix-matrix product, static assert on the two scalar types to be the same.
- Similarly in CwiseBinaryOp. POTENTIALLY CONTROVERSIAL: we don't allow anymore binary
  ops to take two different scalar types. The functors that we defined take two args
  of the same type anyway; also we still allow the return type to be different.
  Again the reason is that different scalar types are incompatible with vectorization.
  Better have the user realize explicitly what mixing different numeric types costs him
  in terms of performance.
  See comment in CwiseBinaryOp constructor.
- This allowed to fix a little mistake in test/regression.cpp, mixing float and double
- Remove redundant semicolon (;) after static asserts
