simplex_constrain() [5/6]

template<bool Jacobian, typename Vec , typename Lp , require_convertible_t< return_type_t< Vec >, Lp > * = nullptr>

plain_type_t< Vec > stan::math::simplex_constrain ( const Vec &  y, Lp &  lp  )

inline

Return the simplex corresponding to the specified free vector.

If the Jacobian parameter is true, the log density accumulator is incremented with the log absolute Jacobian determinant of the transform. All of the transforms are specified with their Jacobians in the Stan Reference Manual chapter Constraint Transforms.

Template Parameters

Jacobian	if true, increment log density accumulator with log absolute Jacobian determinant of constraining transform
Vec	A type inheriting from Eigen::DenseBase or a var_value with inner type inheriting from Eigen::DenseBase with compile time dynamic rows and 1 column
Lp	A scalar type for the lp argument. The scalar type of Vec should be convertable to this.

Parameters

[in]	y	free vector
[in,out]	lp	log density accumulator

Returns

simplex of dimensionality one greater than y
