3e4a68cc60 optimize vectorized reductions by peeling the loop: 
- x2 for squaredNorm() on double
 - peeling the loop with a peeling factor of 4 leads to even better perf
   for large vectors (e.g., >64) but it makes more difficult to keep good performance on smaller ones.

1b98b73472 Refactor force-inlining macros and use EIGEN_ALWAYS_INLINE to force inlining of the integer overflow helpers, whose non-inlining caused major performance problems, see the mailing list thread 'Significant perf regression probably due to bug #363 patches' 2011-11-06 16:27:41 -05:00

ab3f138b23 In the Matrix constructor taking (rows, cols), statically assert that the types are integer. 
The 2D vector ctor taking (x, y) is not concerned.

a594ac3966 Allow for more iterations in SelfAdjointEigenSolver (bug #354). 
Add an assert to guard against using eigenvalues that have not converged.
Add call to info() in tutorial example to cover non-convergence.

9df2f5c923 bug #369 - Quaternion alignment is broken 
The problem was two-fold:
 * missing aligned operator new
 * Flags were mis-computed, the Aligned constant was misused

bca18a13ea The most important inline keyword ever? Without it, gcc failed to inline this function, which is called by all matrix constructors... 2011-10-25 20:45:26 -04:00

1ddf88060b update sparse*sparse product: the default is now a conservative algorithm preserving symbolic non zeros. The previous with auto pruning of the small value is avaible doing: (A*B).pruned() or (A*B).pruned(ref) or (A*B).pruned(ref,eps) 2011-10-24 11:44:53 +02:00

16b638c159 Throw std::bad_alloc even when exceptions are disabled, by doing new int[size_t(-1)]. 
Don't throw exceptions on aligned_malloc(0) (just because malloc's retval is null doesn't mean error, if size==0).
Remove EIGEN_NO_EXCEPTIONS option, use only compiler standard defines. Either exceptions are enabled or they aren't.
