<para>
Uses rlevinson to function convert reflection coefficients to autocorrelation sequence.
</para>
<para>
r = rc2ac(k,r0) finds the autocorrelation coefficients, r, of the output of the discrete-time prediction error filter from the lattice-form reflection coefficients k and initial zero-lag autocorrelation r0
