How to use function structfind properly?

Hello:
When I test structfind ( http://www.mathworks.com/matlabcentral/fileexchange/29808-structfind ), it's working fine. See:
% test run
structfind(object,'pixels',[6 6])
ans =
1
structfind(object,'pixels',[sy sx])
ans =
1
However, inside my code, the function is returning errors. I'm not sure why. See:
% inside the code
sym1 = sy-1; sxm1 = sx-1;
seedIntensity = originalx(sy,sx);
d1 = abs(seedIntensity - originalx(sym1,sxm1));
inObject = structfind(object(w),'pixels',[sym1,sxm1]);
if (d1 < avgInt && isempty(inObject) == 1)
object(w).pixels = [object(w).pixels; sym1 sxm1];
end
Error using == Matrix dimensions must agree.
Error in cmp (line 31) check=all(x==value);
Error in structfind>@(x)(cmp(x,field,value)) (line 88) index=find(arrayfun(@(x)(cmp(x,field,value)),a,'uniformoutput',true));
Error in structfind (line 88) index=find(arrayfun(@(x)(cmp(x,field,value)),a,'uniformoutput',true))
Where originalx is a 2-D array. Can someone help me troubleshoot?

John - put a breakpoint at the line
inObject = structfind(object(w),'pixels',[sym1,sxm1]);
and run your code. When the debugger pauses at the above line, look at each input. What is object(w), what is sym1, what is sxm1?
