SYNOPSIS ^

function [S,ev_strs] = ekf_nmcda_update(S,Y,t,H,R,h,V,CP,CD,pb,alpha,beta,param)

DESCRIPTION ^

EKF_NMCDA_PREDICT  EKF/NMCDA Update step

 Syntax:
   [S,EV_STRS] = ekf_nmcda_update(S,Y,t,H,R,h,V,CP,CD,
                                    a_birth,l_birth,
                                    a_death,l_death,param)

 In:
   S  - Struct array 1xNP of particles
   Y  - Dx1 measurement vector
   t  - Time stamp of the measurement
   H  - Derivative of h() with respect to state as matrix,
        inline function or name of function in
        form H(x,param).
   R  - Measurement noise covariance.
   h  - Mean measurement prediction as vector,
        inline function or name of function in
        form h(x,param). (optional, for default see EKF_UPDATE)
   V  - Derivative of h() with respect to noise as matrix,
        inline function or name of function in
        form V(x,param). (optional, for default see EKF_UPDATE)
   CP - Prior probability of a measurement being due
        to clutter.                               (optional, default zero)
   CD - Probability density of clutter measurements,
        which could be for example 1/V, where V is
        the volume of clutter measurement space.  (optional, default 0.01)
   pb    - Prior probability of birth             (optional, default 0.01)
   alpha - Parameter alpha for the gamma
           distribution model for time to death   (optional, default 1)
   beta  - Parameter beta for the gamma
           distribution model for time to death   (optional, default 10)
   param - Parameters of H, h and V. See, for instance, ekf_predict1 or ekf_update1
           for more details.

 Out:
         S - Predicted struct array of particles
   EV_STRS - Comment strings of happened events

 Description:
   Perform update step of Rao-Blackwellized Monte Carlo
   Data Association Algorithm with Number of Targets estimation.
