inline

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

The transform applied is

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

where $U$ is the constant upper bound.

Template Parameters

T_x	kernel generator expression
T_ub	kernel generator expression

Parameters

[in]	x	unconstrained input
[in]	ub	upper bound

Returns

constrained matrix
