Introduction

This Matrix class is a templated class that can be initialized as any kind of numeric types(int, double,float,& etc). it includes Inverse & determinant functions (which are not so easy to write the code) & also all the operators needed for a Matrix class like Multiplying 2 matrix or multiplying a digit to the matrix. it is able to be any size & also it is easy to use.

Instruction

the uploaded file check.zip contains a file which shows how the Matrix can get initialized & how the operators or functions work. Note that parentheses is maybe the most important operator.it allows you to get access to the array elements ,as :

Member functions of class Matrix

These are all the member functions & operators of the class :

1. Matrix(int Row_Size,int Column_Size)
2. Matrix() >
3. Matrix(const Matrix<T> &)
4. ~Matrix(void)
5. void Set_Element(int Row_,int Column,const T& Value)
6. T Get_Element(int Row ,int Column) const
7. bool operator!() const;
8. const Matrix<T> & operator=(const Matrix<T> &)
9. const Matrix<T> & operator=(const T&)
10. bool operator==(const Matrix<T> &) const
11. bool operator==(const T & ) const
12. bool operator!=(const Matrix<T> & second) const
13. bool operator!=(const T & number)
14. T &operator() (int Row,int Column)
15. Matrix<T> operator+(const T &)
16. Matrix<T> operator+(const Matrix<T> &)
17. const Matrix<T> &operator+=(const T&)
18. const Matrix<T> & operator+=(const Matrix<T> &)
19. Matrix<T> operator-(const T&)
20. Matrix<T> operator - (const Matrix<T> &)
21. const Matrix<T> & operator -=(const T & )
22. const Matrix<T> & operator -=(Matrix<T> & )
23. Matrix<T> operator*(const T&)
24. Matrix<T> operator* (const Matrix<T> &)
25. const Matrix<T> & operator*=(const T&)
26. const Matrix<T> & operator*=(const Matrix<T> &)
27. void Transposed();>
28. Matrix<T> GetTransposed() const
29. bool Inverse();>
30. Matrix<T> GetInversed() const
31. double Det() const
32. void Set_Size(int RowSize,int ColumnSize)
33. const int& Get_ColumnSize() const
34. const int & Get_RowSize() const

• int m_RowSize
• int m_ColumnSize
• T**m_Data

};

Notes

note:The returned argument of Inverse (a boolean ) Shows weather the matrix is Invertible & if it is ,inverts the Matrix

note:I have written this code in vc 2005 but it is not a managed code.if you compile it in vc6 you will see some errors that as an instance i is redeclared .thats because vc6 is alittle differant as when you declare i this way :for (int i=0;i<5;i++){ /*statements*/}

i is destroyed after for statement but in vc6 it is a declared variable even after for statement.but it is easy to change it to vc6 by debugging such errors in vc.you can do it yourself.

Some Technics that are used in Class

to announce one,I have to point to the way the element array (m_Data) is declared using new command:

consider the m_RowSize & m_ColumnSize are given

m_Data=new T* [m_RowSize];

for(int i=0;i<m_RowSize;i++)

m_ColumnSize=new T [m_ColumnSize];
