error in using blkproc

hai i am working with matlab R2009a and i have to move a window of size[30,265] over the image and calculate the sum of pixels inside the window at each location

the problem is my image is having NaN values and and i am using the blkproc function to make the window move over my image and i got a matrix of size 24 X 1 with NAN values is my answer correct please some one help me

and my coding is this

erore=double(eror);
 g=double(g);
final2=imdivide(edgediff,erore);

figure ,image(final2);
% converting nan and inf values to zero  
final2(isnan(final2))=0;
final2(isinf(final2))=0;
[width, height] = size(final2);
%blkproc used to slide and  calucate the sum inside the window
  B=blkproc(final2,[30 height],@(x)sum(x(:)));

and this the result i am getting

We really cannot debug this without knowing what the values of edgediff and eror are like.
