rmle

 RMLE estimates AR Parameters using the Recursive Maximum Likelihood 
 Estimator according to [1]
 
 Use: [a,VAR]=rmle(x,p)
 Input: 
 x is a column vector of data
 p is the model order
 Output:
 a is a vector with the AR parameters of the recursive MLE
 VAR is the excitation white noise variance estimate
