In previous papers the arithmetic of hierarchical matrices has been described, which allows us to compute the inverse, for instance, of finite element stiffness matrices discretising an elliptic ...

Function spaces and operator theory form a rich and interconnected subdiscipline of modern analysis, embracing a variety of spaces that measure function regularity and oscillatory behaviour ...

当我们执行“cout << obj" where obj is an object of our class, the compiler first looks for an operator function in ostream, then it looks for a global function.

The operator to be overloaded should have a corresponding method that is marked with the keyword operator. The arguments to the operator function are operands and your operator function can return ...
