    6565Kalman Filtering</a></h2> 
    6666Kalman filtering is optimal estimation procedure for linear state space model: <p class="formulaDsp"> 
    67 <img class="formulaDsp" alt="\begin{eqnarray} x_t &amp;= &amp;A x_{t-1} + B u_{t} + v_t,\\ y_t &amp;= &amp;C x_{t} + D u_{t} + w_t, \end{eqnarray}" src="form_100.png">

    7070Both prior and posterior densities on the state are Gaussian, i.e. of the class enorm.<p> 
    7171There is a range of classes that implements this functionality, namely:<ul> 
     
    7474Extended Kalman Filtering</a></h2> 
    7575Extended Kalman filtering arise by linearization of non-linear state space model: <p class="formulaDsp"> 
    76 <img class="formulaDsp" alt="\begin{eqnarray} x_t &amp;= &amp;g( x_{t-1}, u_{t}) + v_t,\\ y_t &amp;= &amp;h( x_{t} , u_{t}) + w_t, \end{eqnarray}" src="form_105.png"> 
     76<img class="formulaDsp" alt="\begin{eqnarray} x_t &amp;= &amp;g( x_{t-1}, u_{t}) + v_t,\\ y_t &amp;= &amp;h( x_{t} , u_{t}) + w_t, \end{eqnarray}" src="form_113.png"> 
    7777<p> 
    78  where <img class="formulaInl" alt="$ g(), h() $" src="form_106.png"> are general non-linear functions which have finite derivatives. Remaining variables have the same meaning as in the Kalman Filter.<p> 
     78 where <img class="formulaInl" alt="$ g(), h() $" src="form_114.png"> are general non-linear functions which have finite derivatives. Remaining variables have the same meaning as in the Kalman Filter.<p> 
    7979In order to use this class, the non-linear functions and their derivatives must be defined as an instance of class <code>diffbifn</code>.<p> 
    8080Two classes are defined:<ul>
