% Magnitude spectrum computation (as column vectors)
MAG = abs( fft(frames,nfft,1) );
% Triangular filterbank with uniformly spaced filters on mel scale
H = trifbank( M, K, R, fs, hz2mel, mel2hz ); % size of H is M x K
% Filterbank application to unique part of the magnitude spectrum
FBE = H * MAG(1:K,:); % FBE( FBE<1.0 ) = 1.0; % apply mel floor
% DCT matrix computation
DCT = dctm( N, M );
% Conversion of logFBEs to cepstral coefficients through DCT
CC = DCT *log( FBE );
It shows the error: Error using ==> mtimes Inner matrix dimensions must agree.
Error in ==> new at 47 CC = DCT *log( FBE );

What are the sizes of DCT and FBE? This error is simply telling you that your matrices are not conformable for multiplication like the following:
X = randn(2,3);
Y = randn(2,3);
X*Y
It may be a simple matter of just transposing one matrix, but that is impossible for us to say.
