7ddc13b9fa use a more c++-ish way of preventing the compiler from generating default operator= 
when it's not wanted. Thanks to Christian Mayer for the tip.

fa8009c6b7 1) remove EIGEN_UNUSED, instead use non-named arguments. 
2) use T instead of const T& when that makes more sense
Thanks to Christian Mayer a.k.a Mekhzolan for the tips.

0cbdaf6bb8 revert most of my previous commit. forcing the compiler to inline only increased 
its memory usage.

fc924bc7d4 specialize for Size==0 in order to catch user bugs and not clutter 
the compiler output with an infinite recursion. Also add a #define switch
for loop unrolling.

c58c892e25 had forgotten to 'svn add' that file... 2007-12-05 08:57:23 +00:00

68eba600b1 big reorganisation of asserts, so that: 
0) asserts are only done in the public API, except for a few ones explicitly
   named eigen_internal_assert.
1) internal asserts are disabled unless EIGEN_INTERNAL_DEBUGGING is defined.
   This limits the impact of debugging on performance.
2) no 'unused argument' warnings anymore when compiling with -DNDEBUG

346c00f4c8 Rework the unit-tests to use lower precision, so as to eliminate 
false positives. Also some cleanup in the fuzzy compares.

344623e872 Matrix(int) constructor is only for vectors. 2007-11-26 09:21:11 +00:00
Benoit Jacob
a587346b47 Matrix(int,int) constructor no longer takes default arguments. 
Instead, introduce Matrix() and Matrix(int); however, dynamic dimensions
are required to be specified in the constructor (we no longer default to 1)

884a718b0a make shameless use of const_cast to reduce code redundancy. This means Eigen2 
gives up enforcing constness. I really tried to enforce it, but it really was
much hassle because our expression templates can be lvalues (not only rvalues)
and so much code had to be written twice.

f355ef2df0 Merge WrapArray into FromArray. Less code. The downside is that we're using one more 
const_cast. But I think that anyway trying to maintain const strictness in Eigen2 is not
worth the hassle.

Konstantin: so the code snippet I sent you won't work anymore, replace wrapArray with fromArray.

a94a8c68e8 add fromArray() and wrapArray(). 
For example, the following now works:

  double a1[3] = {1.0, 3.0, 2.0}, a2[3];
  Vector3d::wrapArray(a2) = 2 * Vector3d::fromArray(a1);
  cout << Vector3d::fromArray(a2) << endl; // output: 2,6,4

e445f5085a implement the first _real_ unit-tests, testing the results for correctness instead 
of just checking compilation.

Fix the many issues discovered by these unit-tests, by the way fixing a performance bug.
