Matrix dimensions must agree

i used the builtin Matlab function weiner2 and did the example below... it was an example in the document of weiner function... but i get the below error... please can someone help me rectify it...

 RGB = imread('saturn.png');
 I = rgb2gray(RGB);
 J = imnoise(I,'gaussian',0,0.025);
 K = wiener2(J,[5 5]);
 figure, imshow(K)

 ??? Error using ==> minus
 Matrix dimensions must agree.

 Error in ==> wiener2 at 71
 f = g - localMean;

Running this code on MATLAB R2010b I don't get any error message.

Please give the entire error message, not just a small part snipped out like you did.

The code works just fine for me. I don't get that error.

Like I said, it works fine for me so you must have some other wiener function. What does this say

which -all wiener2

Sorry I can't because, like I said, it works fine for me. You'll have to call the Mathworks for further help because something is messed up with your system since it works on everyone else's.
