#include <boost/qvm/quat_operations.hpp>
namespace boost { namespace qvm { //Only enabled if: is_quat<A>::value template <class A> typename deduce_quat<A>::type inverse( A const & a ); } }
Computes the multiplicative inverse of a, or the conjugate-to-norm ratio.
If the magnitude of a is zero, throws zero_magnitude_error.
If a is known to be unit length, conjugate is equivalent to inverse, yet it is faster to compute.
