Default Compiler Generated Methods | |
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called. | |
ZeroMatrix () | |
Default Constructor. | |
ZeroMatrix (const ZeroMatrix &) | |
Copy Constructor. | |
void | operator= (const ZeroMatrix &) |
Overloaded Equals Operator. |
