dandy is an easy to integrate, single-header linear algebra vector library making use of expression templates for compile-time expression parsing -- as such, operations can be performed on complex vector expressions without the need for intermediary vector allocations.

• lightweight: a single header file with no non-standard external dependencies
• easy to integrate: all vector types can be accessed either under the dd namespace or in the global namespace by adding using namespace dd::types to your source (note that this does not leak any additional symbols). See all types
• supports conversions to and from arbitrary foreign types: in order to more easily integrate with other libraries. Read more
• expression templates: all vector expressions are parsed at compile-time. Read more
• STL integration: overloads for std::ostream operator<<, std::hash::operator() and the inclusion of methods begin() and end() allows the vector to be used in a multitude of standard containers and algorithms

dandy requires C++17 or newer and has been formally tested on MSVC and CLANG.
