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 :

matrix1(2,0)=5;

Member functions of class Matrix

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

template<class T>
class Matrix
{
public:

Matrix(int Row_Size,int Column_Size)
Matrix() >
Matrix(const Matrix<T> &)
~Matrix(void)
void Set_Element(int Row_,int Column,const T& Value)
T Get_Element(int Row ,int Column) const
bool operator!() const;
const Matrix<T> & operator=(const Matrix<T> &)
const Matrix<T> & operator=(const T&)
bool operator==(const Matrix<T> &) const
bool operator==(const T & ) const
bool operator!=(const Matrix<T> & second) const
bool operator!=(const T & number)
T &operator() (int Row,int Column)
Matrix<T> operator+(const T &)
Matrix<T> operator+(const Matrix<T> &)
const Matrix<T> &operator+=(const T&)
const Matrix<T> & operator+=(const Matrix<T> &)
Matrix<T> operator-(const T&)
Matrix<T> operator - (const Matrix<T> &)
const Matrix<T> & operator -=(const T & )
const Matrix<T> & operator -=(Matrix<T> & )
Matrix<T> operator*(const T&)
Matrix<T> operator* (const Matrix<T> &)
const Matrix<T> & operator*=(const T&)
const Matrix<T> & operator*=(const Matrix<T> &)
void Transposed();>
Matrix<T> GetTransposed() const
bool Inverse();>
Matrix<T> GetInversed() const
double Det() const
void Set_Size(int RowSize,int ColumnSize)
const int& Get_ColumnSize() const
const int & Get_RowSize() const

private:

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.

note:the only code i have not written my self is determinant because i have found a great one being written by Paul Bourke .to find the original code go to http://local.wasp.uwa.edu.au/~pbourke/other/determinant/

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];
