problem in glcm graycomatrix code???

Hi.

When I use this code

I = imread('circuit.tif');
glcm = graycomatrix(I,'Offset',[2 0])

I get this error :

Error in graycomatrix (line 167)
[I, Offset, NL, GL, makeSymmetric] = ParseInputs(varargin{:});

Error in Untitled56 (line 2)
GLCM = graycomatrix(I,'Offset',[2 0;0 2]);

Can you help me?

Thank you

Works fine for me:

>> glcm = graycomatrix(I,'Offset',[2 0])
glcm =
       14205        2107         126           0           0           0           0           0
        2242       14052        3555         400           0           0           0           0
         191        3579        7341        1505          37           0           0           0
           0         683        1446        7184        1368           0           0           0

           0           0           0           2        1153        1435           0           0

This also works:

>> GLCM = graycomatrix(I,'Offset',[2 0;0 2])
GLCM(:,:,1) =
       14205        2107         126           0           0           0           0           0
        2242       14052        3555         400           0           0           0           0
         191        3579        7341        1505          37           0           0           0
