template<typename T , typename L , typename U , require_all_kernel_expressions_and_none_scalar_t< T > * = nullptr, require_all_kernel_expressions_t< L, U > * = nullptr>

matrix_cl< double > stan::math::lub_constrain ( const T &  x, const L &  lb, const U &  ub  )

inline

Return the lower and upper-bounded matrix derived by transforming the specified free matrix given the specified lower and upper bounds.

The transform is the transformed and scaled inverse logit,

\(f(x) = L + (U - L) \mbox{logit}^{-1}(x)\)

Template Parameters

T	matrix expression type
L	lower bound expression type
U	upper bound expression type

Parameters

[in]	x	Free matrix to transform.
[in]	lb	Lower bound
[in]	ub	Upper bound

Returns

Lower- and upper-bounded matrix derived from transforming the free matrix.

Exceptions

std::domain_error

if ub <= lb
