Your problem is that Matrix does not have a parameterless constructor. You have already explecitly defined a constructor:
public Matrix(int d, int c)
{
Dong = d;
Cot = c;
mt=new int[3,3];
}
If you want to have to posibility of create a Matrix without (int d, int c) then defined an explicit one like this:
public Matrix():this( 10, 10) {};
Here you hare initializing your Matrix with 10. This is a default value. You may use whatever you one. Even if you dont want to specify one default value.
Constructor overloading: You can have more than one constructor with different signatures. If you invoke a constructor that is not defined then the compiler complains except when you dont define anyone.
