SolidWorks 2022 学习（一）软件安装接下来是安装SolidWorks，右键SolidWorks.2022.SP0.Premium.DVD.iso，选择装载。然后以管理员身份运行SolidWorks_Flexnet_Server目录下的server_install.bat。更改需要安装的产品，以及安装路径，并勾选接受条款，点击现在安装，会弹出如下窗口。然后以管理员身份运行setup.exe，开始安装solidworks。下载链接会在文章末尾给出，下载完成的文件如下图所示。双击注册表文件，然后点击确定。保持不动，点击确定，开始安装。阅读详情

小弟做了一个简单的矩阵算法，编译完源文件后link出问题。好像是找不到函数，但是以下函数都有定义，也在main中include了，不知道错在哪里，恳请各位大虾指点！万分感激！

头文件如下：
#ifndef _COMPLEX_H_
#define _COMPLEX_H_

#include <iostream>

using std::istream;
using std::ostream;

template <class D> class complex
{
friend ostream &operator<<(ostream &, const complex<class D> &);
friend istream &operator>>(istream &, complex<class D> &);

public:
complex (D=0.0, D=0.0); //constructor
complex operator+(const complex &) const; //plus
complex operator-(const complex &) const; //minus
complex operator*(const complex &) const; //multiplication
complex operator/(const complex &) const; //division
complex &operator=(const complex &); //overload assign
D real() const; //get real part
D imag() const; //get imaginary part
complex & conj(); //get conjugate
bool operator==(const complex &); //equal
bool operator!=(const complex &); //unequal
void Print() const; //output

private:
D rl; //real part
D im; //imaginary part
};
#endif

错误信息如下：
