@@ -120,6 +120,8 @@ run time. However, these assertions do cost time and can thus be turned off.
- \b \c EIGEN_STACK_ALLOCATION_LIMIT - defines the maximum bytes for a buffer to be allocated on the stack. For internal
temporary buffers, dynamic memory allocation is employed as a fall back. For fixed-size matrices or arrays, exceeding
this threshold raises a compile time assertion. Use 0 to set no limit. Default is 128 KB.
- \b \c EIGEN_NO_CUDA - disables CUDA support when defined. Might be useful in .cu files for which Eigen is used on the host only,
and never called from device code.
- \c EIGEN_DONT_ALIGN - Deprecated, it is a synonym for \c EIGEN_MAX_ALIGN_BYTES=0. It disables alignment completely. %Eigen will not try to align its objects and does not expect that any objects passed to it are aligned. This will turn off vectorization if \b EIGEN_UNALIGNED_VECTORIZE=1. Not defined by default.
