Hi,
I have a cell array, cell_array, and I am trying to calculate the mean of all the elments in each column of it's subcomponent, cell_array{3,1}:
cell_array_mean_vals=cell(1,6) %cell_array is 4x6 and cell_array_mean_vals is initialised to be 1x6
for i=1:size(cell_array{3,1},2)
cell_array_mean_vals{1, i}=mean2(cell_array{3,1}(:,i));
end
Error: mean2 requries the image processing toolbox and i cant use 'mean' or 'sum' because cell_array{3,1} contains doubles
Thank you

Of courser you can use mean and sum for double arrays. Why do you think, that this is not possible?
cell_array{3,1} = magic(4); % Some test data
for i=1:size(cell_array{3,1},2)
cell_array_mean_vals{1, i} = mean(cell_array{3,1}(:,i));
end
cell_array_mean_vals
% And without a loop:
result2 = num2cell(mean(cell_array{3,1}, 1))
