Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

This is an older version of Boost and was released in 2018. The current version is 1.90.0.

mref

QVM: Quaternions, Vectors, Matrices

mref

#include <boost/qvm/mat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if: is_mat<A>::value
        template <class A>
        -unspecified-return-type- mref( A & a );
    }
}

Returns:

An identity view proxy of a; that is, it simply accesses the elements of a.

This allows calling Boost QVM operations when a is of built-in type, for example a plain old C array.
