Documentation

Produce a set linear prediction coefficients from a frame of speech waveform. sig is the frame of input waveform, and lpc are the LPC coefficients. The order of the lpc analysis is given as the size of the lpc vector -1. The coefficients are placed in the locations 1 - size, and the energy is placed in location 0.
