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 see also ACOVF ACORF DURLEV REFERENCES: P.J.
