If you want to define Matrix Operations in a class like way. You need to look at a matrix as an object (not a thing that holds three matrixes).
###Matrix as an object.
Matrix as an object.
What are the properties of a matrix?
1) Width
2) Height
3) Values (Data)
What are the action that can be performed on a matrix.
1) Sum
2) Diff
3) Transpose
Looking at these properties I would define the following.
class Matrix
{
std::size_t width;
std::size_t height;
std::vector<int> data;
public:
Matrix sum(Matrix const& rhs);
Matrix diff(Matrix const& rhs);
Matrix transpose();
};
You also need to define a couple of standard functions (or disable some standard functions).
class Matrix
{
public:
// Create a matrix (of specified width/height with all data set to zero
Matrix(int width, int height);
// Copy a matrix
Matrix(Matrix const& copy);
// Allow people to set matrixes via assignment
Matrix operator=(Matrix const& copy);
// Input and output operations so you can print a matrix
// And read a matrix from a stream (stdin/stdout)
friend std::ostream operator<<(std::ostream& str, Matrix const& output);
friend std::istream operator>>(std::istream& str, Matrix& input);
};
Once you have defined these you should be all set.
