> Calulate cepstral coefficients from lpc coefficients.

> It is possible to calculate a set of cepstral coefficients from lpc coefficients using the relationship:

> The order of the cepstral analysis can be different from the lpc order. If the cepstral order is greater, interpolation is used (FINISH add equation). Both orders are taken from the lengths of the respective vectors. Note that these cepstral coefficients take on the assumptions (and errors) of the lpc model and hence will not be the same as cepstral coefficients calculated using DFT functions.

Parameters:
  lpc - : the LPC coefficients (input)
  lpc - : the cepstral coefficients (output)
