WebDec 3, 2012 · Eigen::Quaternion (1,0,0,0); … WebThe EIGEN_DONT_ALIGN option still exists in Eigen 3, but it has a new cousin: EIGEN_DONT_ALIGN_STATICALLY. It allows to get rid of all static alignment issues while keeping alignment of dynamic-size heap-allocated arrays, thus keeping vectorization for dynamic-size objects. Aligned Map objects WebIf you want to know why defining EIGEN_DONT_VECTORIZE does not by itself disable 16-byte alignment and the assertion, here's the explanation: It doesn't disable the assertion, because otherwise code that runs fine without vectorization would suddenly crash when enabling vectorization. manufacturing batch recipe examples
