如何将矩阵类转换为模板类

Question

我有我的任务，需要非常严格的帮助 - 你是否愿意回答这个问题呢？

1 - 将Matrix类转换为模板类。使用合适的主函数测试矩阵模板，该函数声明复数矩阵，键盘/文件输入和屏幕/文件输出。

因此原始代码如下

#ifndef MATRIX_H  //include guard
#define MATRIX_H

#include <iostream>  //generic IO
#include <fstream>   //file IO
#include <stdexcept> //provides exceptions
#include "vector.h"  //we use Vector in Matrix implementation

class Matrix {
private:
    Vector v;     // Vector used to store the matrix elements
    int nrows;    // number of rows of the matrix
    int ncols;    // number of columns of the matrix

public:
    // CONSTRUCTORS
    Matrix(); // default constructor, uses default constructor for v
    Matrix(int Nrows, int Ncols);  // alternate constructor
    Matrix(const Vector& v); // build a matrix from a vector
    Matrix(const Matrix& m); // copy constructor

    // ACCESSOR METHODS
    int getNrows() const; // get the number of rows
    int getNcols() const; // get the number of cols

    // OVERLOADED FUNCTION CALL OPERATORS
    double& operator() (int i, int j); //  function call overload (-,-) for assignment
    double operator() (int i, int j) const; // for reading matrix values
    Matrix& operator=(const Matrix& m); // overloaded assignment operator
    bool operator==(const Matrix& m) const; // overloaded comparison operator

    // INPUT & OUTPUT 
    friend std::istream& operator>>(std::istream& is, Matrix& m);// keyboard input
    friend std::ostream& operator<<(std::ostream& os, const Matrix& m);// screen output

    //the file output operator is compatible with file input operator,
    //ie. everything written can be read later.
    friend std::ifstream& operator>>(std::ifstream& ifs, Matrix& m);// file input
    friend std::ofstream& operator<<(std::ofstream& ofs, const Matrix& m);// file output
};

// Note: There is no strict need for a copy constructor or 
// assignment operator in the Matrix class since the 
// compiler versions of these methods will work OK. It will copy/assign 
// the values of nrows and ncols and call the Vector copy 
// constructor/assignment operator automatically for the 
// Vector part v inside the Matrix. However they are written
// for clarity and understanding

#endif

为了将其转换为模板，我使用模板

更改了功能

#ifndef MATRIX_H  //include guard
#define MATRIX_H

#include <iostream>  //generic IO
#include <fstream>   //file IO
#include <stdexcept> //provides exceptions
#include "vector.h"  //we use Vector in Matrix implementation

class Matrix {
    template <typename T> class T
protected:
    Vector v;     // Vector used to store the matrix elements
    int num; // Number of elements
    int nrows;    // number of rows of the matrix
    int ncols;    // number of columns of the matrix
    T* pdata; // Pointer to the data
    void Init(int Num); // private function since user should not call it

public:
    // CONSTRUCTORS
    Matrix(); // default constructor, uses default constructor for v
    Matrix(int Nrows, int Ncols);  // alternate constructor
    Matrix(const Matrix& v); // build a matrix from a vector
    Matrix(const Matrix& m); // copy constructor

    // SIZE
    int size() const; //get number of elements in the vector

    // ACCESSOR METHODS
    int getNrows() const; // get the number of rows
    int getNcols() const; // get the number of cols

    // OVERLOADED FUNCTION CALL OPERATORS
    Matrix<T>& operator() (int i, int j); //  function call overload (-,-) for assignment
    T& operator() (int i, int j) const; // for reading matrix values
    T operator[] (int i) const; // overloaded array access operator for reading
    Matrix& operator=(const Matrix& m); // overloaded assignment operator
    bool operator==(const Matrix& m) const; // overloaded comparison operator

    // INPUT & OUTPUT 
    friend std::istream& operator>>(std::istream& is, Matrix& m);// keyboard input
    friend std::ostream& operator<<(std::ostream& os, const Matrix& m);// screen output

    //the file output operator is compatible with file input operator,
    //ie. everything written can be read later.
    friend std::ifstream& operator>>(std::ifstream& ifs, Matrix& m);// file input
    friend std::ofstream& operator<<(std::ofstream& ofs, const Matrix& m);// file output
};

// Note: There is no strict need for a copy constructor or 
// assignment operator in the Matrix class since the 
// compiler versions of these methods will work OK. It will copy/assign 
// the values of nrows and ncols and call the Vector copy 
// constructor/assignment operator automatically for the 
// Vector part v inside the Matrix. However they are written
// for clarity and understanding

#endif

最后测试我在另一个类

输入的Matrix

   #include <iostream>
#include <cmath>
#include <vector.h>
#include <complex.h>
#include <matrix.h>


Matrix<Complex> matrix_vector(10);

    std::cin >> matrix_vector;

请，我收到错误，并不完全确定我在所有地方是否正确。我非常感谢。非常感谢
