Routine mAR1psd: To compute the power spectum by AR-model pARameters.
Input pARameters:
ip : AR model order (integer)
ep : White noise vARiance of model input (real)
ts : Sample interval in seconds (real)
a : Complex ARray of AR pARameters a(0) to a(ip)
Output pARameters:
psdr : Real ARray of power spectral density values
psdi : Real work ARray
