这个函数接受一个std::array<double, 3>类型的参数,并返回一个Eigen::Vector3d对象,通过直接访问数组元素并传递给Eigen::Vector3d的构造函数来实现转换。 测试转换函数: 在编写完转换函数后,我们需要进行测试以确保其正确性。以下是一个简单的测试示例: cpp #include <iostream> #include <array...
Vector Vector描述的是一个动态数组(dynamic array),并提供了相关操作和接口。 在使用Vector之前,需要引入头文件#include<vector>,在此头文件中,类型vector是一个定义于namespace std内的template: 1 2 3 4 其中T可以是任意类型,Allocator用来定义内存模型,默认是C++标准库提供的alloc...std...
Method 1is probably the easiest to understand. Just copy each element from the array and push it into the back of the vector. Alas, it's slow. Because there's a loop (implied with the copy function), each element must be treated individually; no performance improvements can be made based...
