var=cell(CC.NumObjects,1)
for j=1:1:n
% clear var
var(j,1)= var(double(image(CC.PixelIdxList{1,j})))
end
%
my code is like this. CC.NumObjects=10 and for example its consists of CC.PixelIdxList{1,1} = 369x1 array. Others consist of arrays like this. "CC.Pixel dxList{1,1}" values in this are pixel indices. I'm trying to measure the variance of the values corresponding to these indices in the image matrix. but it gives this error.

Attach the data you are working with. Use the paperclip button to do so.
Once again, why are you trying to use an empty cell array as a variable as and then over-writing it?
var{j,1} = var(double(image(CC.PixelIdxList{1,j})));

Avoid naming your variable var, since that is the name of a function you are trying to use. Also, a cell array doesn't appear to be required; you can use a numeric vector to store the results.
var_result = zeros(n,1);
for j = 1:n
var_result(j,1) = var(double(GPR(CC.PixelIdxList{1,j})));
end
