But the most extensive form of the CAPTAIN Toolbox was developed in the <em>Environmental Science Department<\/em> (now part of the <em>Lancaster Environment Centre<\/em>) at Lancaster starting in the mid 1980&#8217;s, when Dr Wlodek Tych introduced us to Matlab and started the &#8216;CAPTAINization&#8217; of the constituent algorithms \u00a0into a \u00a0Matlab form that could be called easily for use in Matlab. These algorithms are multifarious, covering topics in the statistical identification and recursive estimation of discrete and continuous-time transfer function models; associated and other forecasting procedures; and the digital control of dynamic systems using a <em>Non-Minimal State Space<\/em> (NMSS) formulation.
