This function provides espectral estimate which is maximum entropy stisfying correlation constraint(number of poles) and cepstrum constraints (number of ceros).
The function requeries: input signal, order of denominator, order of numerator.
ARMA_LAST function requires spa_corc.m file to compute the autocorrelation matrix
