arcext

 ARCEXT extracts AR and RC of order P from Matrix MX
 function  [AR,RC] = arcext(MX,P);

  INPUT:
 MX     AR and RC matrix calculated by durlev 
 P     model order (default maximum possible)

  OUTPUT
 AR    autoregressive model parameter    
 RC    reflection coefficients (= -PARCOR coefficients)

 All input and output parameters are organized in rows, one row 
 corresponds to the parameters of one channel
