The Symbol class

class codegenvar::Symbol

The class Symbol is the main class of the CppCondegenVar project.

Constructors

A Symbol object can be initialized as a named symbol or a constant.

Symbol x("x"), y("y"), zero(0), c3(3.0);
auto vars = Symbol::Array("a", "b", "c", 0, 3.14);

template <class… Args>
