定量金融是一个高度复杂的跨学科领域,涵盖了数学、金融和信息技术。成功地驾驭它需要来自许多来源的专业知识,如金融衍生品、随机微积分和蒙特卡洛模拟。至关重要的是,它还需要将理论有效地转化为实践的能力。 在《使用 C++进行高级定量金融》中,我们将带领读者进入这个激动人心的领域。解释了用于定价金融衍生品的关键数...

即使非用这种特性不可，也请先考虑使用带SSO（小对象优化）的vector如llvm::SmallVector。
接下让看会调用VelocityIterator的SimpleTrajectoryGenerator::initialise。 void SimpleTrajectoryGenerator::initialise( const Eigen::Vector3f& pos, const Eigen::Vector3f& vel, const Eigen::Vector3f& goal, base_local_planner::LocalPlannerLimits* limits, const Eigen::Vector3f& vsamples, bool discretize_...

Deinitialises the vector, freeing the memory the vector allocated during use; this should be called when we're finished with a vector. vec_push(v, val) Pushes a value to the end of the vector. Returns 0 if the operation was successful, otherwise -1 is returned and the vector remains ...

From this, it does look like there is an issue with the 64-bit integer interface and BLACS tags/IDs that I'm assuming is then causing the eigensolvers to hang/error. I have attached the code I used to generate the above outputs which...
The exception kind is recorded in the global register3 Sys.Indicators, which is a bit vector with a bit for every kind of exception. To find out which exception has ocurred, C-- provides some predefined global constants. They are also bit vectors, with the particular bit that encodes the ...
