unit_vector_free() [1/2]

template<typename EigVec , require_eigen_col_vector_t< EigVec > * = nullptr>

auto stan::math::unit_vector_free ( EigVec &&  x )

inline

Transformation of a unit length vector to a "free" vector However, we are just fixing the unidentified radius to 1.

Thus, the transformation is just the identity

Template Parameters

EigVec

A type derived from EigenBase with 1 compile time row or column.

Parameters

x	unit vector of dimension K

Returns

Unit vector of dimension K considered "free"
