When the mfcc function uses the default parameters, it outputs 13 mel-frequency cepstral coefficients, and appends the log-energy (for a total of 14 elements per frame). Most applications that use MFCC append the log-energy to the feature vector. To ignore the log-energy, set the "LogEnergy" parameter to 'ignore'.
