MHTLLR:

--------------------------------------------------------------------------
   Update the log likelihood ratio.

   Type MHTLLR for a demo of having a sequence of no detections.
--------------------------------------------------------------------------
   Form:
   LLR = MHTLLR( lLR, alpha, beta, s, d, isDet )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   lLR           (1,1) Log likelihood ratio
   alpha         (1,1) Probability of false alarm
   beta          (1,1) Probability of missed detection
   s             (:,:) Covariance matrix for states
   d             (:,1) Residual vector
   isDet         (1,1) 1 if the target is detected

   -------
   Outputs
   -------
   lLR           (1,1) Log likelihood ratio
