# 使用Eigen库处理线性代数问题

> 创建时间：2024/1/14 15:17

## Overview

Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

Eigen一个重要特点是没有什么依赖的库，本身仅有许多头文件组成，因此非常轻量而易于跨平台。你要做的就是把用到的头文件和你的代码放在一起就可以了。

## VS Project中配置

  1. 下载：http://eigen.tuxfamily.org/index.php?title=Main_Page
  2. 解压后将Eigen subdirectory解压到方便的位置
  3. 新建VS Console Project
  4. 右键相应的Project -> Properties -> Configuration Properties -> C/C++ -> General -> Additional Include Directories 。 将Eigen文件夹的父目录路径加进去
  5. `#include "Eigen/Dense"` 即可开始试用

## Demos

```cpp
string str1 = "test";
string str2 = "test";

```
```cpp
string str1 = "test";
string str2 = "test";

```
