ARMA PARAMETER ESTIMATION

Estimating the parameters of AR-MA sequences is fundamental. Here we present another method for ARM

File name: ARMA_LAST.M

This function provides an ARMA spectral estimate which is maximum entropy satisfying correlation constraint (number of poles)and cepstrum
constrains (number of ceros)

The function requires 3 inputs: Input signal, Order of denonominator, Order of Numerator and the output variable are: numerator coeffients, denominator coeficients and square-root of input noise power.

ARMA_LAST function requires spa_corc.m file to compute the autocorrelation matrix
