control (List[qctrl.dynamic.types.ComplexSegmentInput]) – The list of segments, pairs of a duration and a value \(\{(\delta
t_{\gamma_{j},n}, \gamma_{j,n})\}\), that define the piecewise-constant
control \(\gamma_{j}(t)\). This means that \(\gamma_{j}(t) =
\gamma_{j,n}\) for \(t_{\gamma_{j},n-1} \leq t < t_{\gamma_{j},n}\),
where \(t_{\gamma_{j},0} = 0\) and \(t_{\gamma_{j},n} =
t_{\gamma_{j},n-1} + \delta t_{\gamma_{j},n}\). You must provide at
least one segment.
