how to read multiple .wav file from other .m file

B = importdata('allfeaturesongs.m');

for i=1:5

[y, fs]=wavread(B(i)); t1=[1/fs:1/fs:length(y)/fs]; fprintf('Duration orignl = %g seconds\n', length(y)/fs); nsamples = 20 * fs; [y2, fs] = wavread(B(i), nsamples); %sound(y2, fs); t2=[1/fs:1/fs:length(y2)/fs]; fprintf('Duration splited = %g seconds\n', length(y2)/fs); figure,ax(1)=subplot(3,1,1);plot(t1,y);title('orgnl');title(B(i));xlabel('Time (sec)'); ax(2)=subplot(3,1,2);plot(t2,y2);title('splited');title('splited');xlabel('Time (sec)');

end

here is code but is gives me error like this

Warning: WAVREAD will be removed in a future release. Use AUDIOREAD instead. > In wavread at 62 In trywaystore at 6 Error using fileparts (line 33) Input must be a row vector of characters.

Error in wavread>open_wav (line 194) [pat,nam,ext] = fileparts(file);

Error in wavread (line 68) [fid,msg] = open_wav(file);

Error in trywaystore (line 6) [y, fs]=wavread(B(i));

how to solve this problem??? please give me solution thanx in advance
