lb_constrain() [5/17]

template<typename T , typename L , require_all_stan_scalar_t< T, L > * = nullptr, require_all_not_st_var< T, L > * = nullptr>

auto stan::math::lb_constrain ( T &&  x, const L &  lb  )

inline

Return the lower-bounded value for the specified unconstrained input and specified lower bound.

The transform applied is

\(f(x) = \exp(x) + L\)

where \(L\) is the constant lower bound.

Template Parameters

T	Scalar.
L	Scalar.

Parameters

[in]	x	Unconstrained input
[in]	lb	Lower bound

Returns

Constrained matrix
