std::vector<Eigen::Vector4f,Eigen::aligned_allocator<Eigen::Vector4f> > 针对vector的时候,还需要额外添加头文件#include<Eigen/StdVector> 在对象定义的时候,使用特殊的宏 EIGEN_DEFINE_STL_VECTOR_SPECIALIZATION(Matrix2d) 注意必须在所有Eigen对象出现前使用这个宏 有这个问题的Eigen结构包括: 1Eigen::Vector2d...

public: std::vector<Eigen::Vector3d> points_; std::vector<Eigen::Vector3d> normals_; std::vector<Eigen::Vector3d> colors_; and I am curious why this attributes are not crashing. Here is another reference: SBA in ROS that explicitly declares Eigen::aligned_allocator. syncle changed the...
在C++中,可以通过以下步骤将std::vector操作转换为Eigen::VectorXf: 1. 首先,确保已经包含了Eigen库的头文件,例如: ```cpp #include <...
Eigen::Matrix2Xd points; ...std::vector<Eigen::Vector2d>v_points(points.data() Eigen::aligned_allocator<Eigen::vector2d>(points_data())) This is possible using a custom allocator as described there:Is it possible to initialize std::vector over already allocated memory?
std::vector<float> mOutputData; mOutputData = std::vector<float>{ output, output + sizeof(arrHeight)/sizeof(float) }; float* a 赋值给float* b float* inputdata float* hostDataBuffer; std::memcpy(hostDataBuffer, inputdata, numbers * sizeof(float)); std::vector 转化为Eigen::Matrix ...
通过循环遍历矩阵的每一列,将每一列作为Eigen::VectorXf类型的向量,然后将向量添加到std::vector<Eigen::Vector>中。 现在,vec中就存储了矩阵映射后的结果,可以对其进行进一步的操作或使用。 总结: Eigen是一个用于线性代数计算的C++模板库,可以通过Map函数将Eigen矩阵映射到std::vector<Eigen::Ve...
I have an a Eigen::MatrixXd that I made from std::vector of Eigen::Vector3d. It was easy. I made some transform manipulation on that matrix and I want return result as std vector of Eigen::Vector3d. How could I make std::vector<Eigen::Vector3d> form Eigen::Matrix3d? c++ std ...
