unit_vector_constrain() [9/11]

template<typename T , require_std_vector_t< T > * = nullptr>

auto stan::math::unit_vector_constrain ( const T &  y )

inline

Return the unit length vector corresponding to the free vector y.

This overload handles looping over the elements of a standard vector.

Template Parameters

T	A standard vector with inner type inheriting from Eigen::DenseBase or a var_value with inner type inheriting from Eigen::DenseBase with compile time dynamic rows and 1 column

Parameters

y	vector of K unrestricted variables

Returns

Unit length vector of dimension K

See https://en.wikipedia.org/wiki/N-sphere#Generating_random_points

Template Parameters

EigMat

type inheriting from EigenBase that has a var scalar type.

Parameters

y	vector of K unrestricted variables

Returns

Unit length vector of dimension K
