error in program

HI

>>[FileName,PathName]=uigetfile('sampleleft.wav');
>> PathOrig=sprintf('%s%s',PathName,FileName);
>> [x,fs]=wavread(PathOrig);
>> [FileName1,PathName1]=uigetfile('sampleright.wav');
>> PathOrig1=sprintf('%s%s',PathName1,FileName1);
>> [y,fs]=wavread(PathOrig1);
>> cccorrelation=xcorr(y,x);

Error using xcorr>parse_y (line 314)
B must be a vector (min(size(B))==1).

Error in xcorr>parseinput (line 290)
  maxlag = parse_y(y,m,xIsMatrix,maxlag);

Error in xcorr (line 48)
[xIsMatrix,autoFlag,maxlag,scaleType] = parseinput(x,varargin{:});

could you please tell me how to handle this error?

thanks in advance

Something is wrong with your x vector from

[x,fs]=wavread(PathOrig);

Please show us what is returned if you enter

>>whos x

Name Size Bytes Class Attributes

x 440320x2 7045120 double

[Padma]

it showed the same for y also

It seems like x is empty. Please try this:

[FileName, PathName] = uigetfile('sampleleft.wav');
PathOrig  = fullfile(PathName, FileName);
[x, fs1]  = wavread(PathOrig);
[FileName1, PathName1] = uigetfile('sampleright.wav');
PathOrig1 = fullfile(PathName1,FileName1);
[y,fs]    = wavread(PathOrig1);
disp(size(x));
disp(size(y));

i tried display, it gave 440320 2 for both x and y

Your x and y are two channels -- and that means they are not vectors. You need to correlate one channel against one channel.
