https://en.cppreference.com/w/cpp/language/explicit17.01.2022 · 1) Specifies that a constructor or conversion function (since C++11) or deduction guide (since C++17) is explicit, that is, it cannot be used for implicit conversions and copy-initialization. 2) The explicit specifier may be used with a constant expression. The function is explicit if and only if that constant expression evaluates to true.
Explicit and implicit methods - Wikipedia
https://en.wikipedia.org/wiki/Explicit_and_implicit_methodsExplicit and implicit methods are approaches used in numerical analysis for obtaining numerical approximations to the solutions of time-dependent ordinary and partial differential equations, as is required in computer simulations of physical processes. Explicit methods calculate the state of a system at a later time from the state of the system at the current time, while implicit methods find a solution by solving an equation involving both the current state of the system and the later one…
