Routine marburg: To estimate the AR parameters by Burg algorithm.

Input Parameters:

n : Number of data samples

ip : Order of autoregressive process

x : Array of complex data samples x(0) through x(n-1)

Output Parameters:

ep : Real variable representing driving noise variance

a : Array of complex AR parameters a(0) to a(ip)

ierror=0 : No error

=1 : ep<=0 .



ef : complex work array. ef[0] to ef[n-1]

eb : complex work array. eb[0] to eb[n-1]
