ub_constrain() [1/14]

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

auto stan::math::ub_constrain ( T &&  x, U &&  ub  )

inline

Return the upper-bounded value for the specified unconstrained matrix and upper bound.

The transform is

$f(x) = U - \exp(x)$

where $U$ is the upper bound.

Template Parameters

T	type of Matrix
U	type of upper bound

Parameters

[in]	x	free Matrix.
[in]	ub	upper bound

Returns

matrix constrained to have upper bound
