tmp_fea = cqcc(x, fs, B, fmax, fmin, d, cf, 'ZsdD');

tmp_fea1 = melcepst(x, fs, '0dD', n_MFCC, floor(3*log(fs)) ,frame_length * fs, frame_hop * fs, fl, fh)';

fea = [tmp_fea tmp_fea1];

Well, as far as I can see, cqcc is a function with input-variables (x, fs, B, fmax, fmin, d, cf) and one input-string ('ZsdD'). The same occurs with the function melcepst, where 'OdD' is also an input-string. So, 'ZsdD' and 'OdD' are not variables, but character-strings.

What the programmer tries to do? No idea, for an answer one must check the source-code of the functions cqcc and melcepst.
