Problem in filterbank application to unique part of the magnitude spectrum

      % Filterbank application to unique part of the magnitude spectrum
        FBE = H * MAG;%(1:K,:); % FBE( FBE<1.0 ) = 1.0; % apply mel floor

Can you be more specific? What error are you getting? Are you actually trying to apply the following code (literally)

FBE = H*MAG;%(1:K,:);

Please format the code as you are entering it in MATLAB and report the error message.
