poly2rc() - Signal Processing

k = poly2rc(a) converts
the prediction filter polynomial a to the reflection
coefficients of the corresponding lattice structure. a can
be real or complex, and a(1) cannot be 0. If a(1) is
not equal to 1, poly2rc normalizes
the prediction filter polynomial by a(1). k is
a row vector of size length(a)-1.[k,r0] = poly2rc(a,efinal) returns the zero-lag
autocorrelation, r0, based on the final prediction
error, efinal.


k = poly2rc(a)[k,r0] = poly2rc(a,efinal)


stable = all(abs(poly2rc(a))<1)
