identity_constrain()

template<bool Jacobian = false, typename T , typename... Types, require_all_not_var_matrix_t< T, Types... > * = nullptr>

auto stan::math::identity_constrain ( T &&  x, Types &&  ...  )

inline

Returns the result of applying the identity constraint transform to the input.

This promotes the input to the least upper bound of the input types.

Template Parameters

Jacobian	if true, increment log density accumulator with log absolute Jacobian determinant of constraining transform
T	type of value to promote
Types	Other types.

Parameters

[in]

x

object

Returns

transformed input

This specialization handles convert Eigen matrices of doubles to var matrix types.

Template Parameters

T	Any type.
Types	Any type with one of T and Types being a var_value matrix.

Parameters

[in]

x

object

Returns

transformed input
