Sample Code to Reproduce
#include <iostream>
#include <Eigen/Core>
int main(int argc, char** argv)
{
//1.方阵
Eigen::Matrix3f A; //本质是Eigen::Matrix<float,3,3> A;
A << 1,2,3,4,5,6,7,8,9;
std::cout << "A= \n" << A << std::endl;
//2. 转置操作
Eigen::Matrix3f A_T = A.transpose();
std::cout << "\nA的转置矩阵A_T= \n" << A_T << std::endl;
//3. 零矩阵
Eigen::Matrix<float,3,5> B = Eigen::Matrix<float,3,5>::Zero();
std::cout << "\nB= \n" << B << std::endl;
//4. 对角矩阵
//4.1 构造对角矩阵
Eigen::VectorXd vector(5); //构建5维向量
vector<<1,2,3,4,5; //向量赋值
Eigen::MatrixXd C(vector.asDiagonal()); //使用向量生成对角阵
std::cout << "\nC= \n" << C << std::endl;
//4.2 从普通矩阵中提取对角元素组成向量
std::cout << "\n从C中提取对角元素构成向量= \n" << C.diagonal() << std::endl; //C也可以不是方阵
//5. 单位矩阵
//5.1 构造单位矩阵
Eigen::Matrix3f D = Eigen::Matrix3f::Identity(); //简写
Eigen::Matrix<float,4,4> E = Eigen::Matrix<float,4,4>::Identity(); //完整写法
std::cout << "\n单位矩阵D= \n" << D << std::endl;
std::cout << "\n单位矩阵E= \n" << E << std::endl;
//5.2 构造对角线为1的普通矩阵
Eigen::Matrix<float,3,5> F = Eigen::Matrix<float,3,5>::Identity();
std::cout << "\n普通对角元素为1的矩阵F= \n" << F << std::endl;
return 0;
}Expected behavior
