eigen::vector

Eigen::Vector is a class template provided by the Eigen library for C++. It is used to represent a vector of elements of a given data type (e.g. double, float, int) and size.

Eigen::Vector provides a number of useful operations for working with vectors, including vector addition, subtraction, dot product, cross product, and normalization. It also supports slicing and indexing operations, making it easy to access individual elements or subsets of elements within a vector.

One of the key benefits of using Eigen::Vector is its performance. The library is designed for high-performance computing and uses a number of optimization techniques to ensure that vector operations are executed as quickly as possible. This makes it a popular choice for applications in fields such as machine learning, computer vision, and robotics.

Overall, Eigen::Vector is a powerful and flexible tool for working with vectors in C++. Whether you need to perform simple vector operations or complex computations, Eigen::Vector has the features and performance you need to get the job done.
