Is there any way to tell Eigen where to allocate memory during Dynamic allocation? My current code structure involves allocating a large amount of memory at the beginning of the program and carving pieces out when ever I allocate memory in the program. Is it possible to integrate Eigen into the structure?

Thanks!

There is no easy solution for that yet. An ugly workaround would consists in adding overloads of the following template functions:

Code: Select all

template<typename T, bool Align> EIGEN_DEVICE_FUNC inline T* conditional_aligned_new_auto(size_t size);
template<typename T, bool Align> inline T* conditional_aligned_realloc_new_auto(T* pts, size_t new_size, size_t old_size);
template<typename T, bool Align> EIGEN_DEVICE_FUNC inline void conditional_aligned_delete_auto(T *ptr, size_t size);


See src/Core/utils/Memory.h file. You need to add overloads for each scalar type you need.
