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_x	type of unconstrained input
T_lb	type of lower bound

Parameters

[in]	x	unconstrained input
[in]	lb	lower bound

Returns

constrained matrix
