lpc Linear prediction filter coefficients [a,g] = lpc(x) [a,g] = lpc(x,p) [a,g] = lpc(x,p) Determines the coefficients of a pth order forward linear predictor filter by minimizing the squared error. If p is unspecified, a default value of length(x)-1 is used. x: double p: int, natural number, scalar a: double g: double
