Dear all,
I have a cell array of 31x12x9 and in every cell is a 288x3 structure. I want to delete every cell wich has not the 288x3 structure. So all have x3 but the value 288 is in some cells different and these should be deleted! Thank you in advance!

Hi Thor, try the following:
% Create dummy data.
S = cell(1,2,2);
l1(288,3).Value = 1; l2(280,3).Value = 1;
S{1,1,1} = l1; S{1,1,2} = l2; S{1,2,1} = l1; S{1,2,2} = l1;
K = S(cell2mat(cellfun(@(x) size(x,1), S, 'UniformOutput', false))==288);

Your cell array is A of size m=31, n=12 , p=9 :
for x=1:m
for y=1:n
for z=1:p
if(size(A{x,y,z},1)~=288 && size(A{x,y,z},2)~=3)
A{x,y,z}=[];
end
end
end
end

If C is your data cell:
C(cellfun('size', C, 1) ~= 288) = {[]};
Here the contents of the not matching cell elements are deleted, but not the cells itself. If you want to delete the cells, the result cannot be a cell array anymore but a cell vector only:
C = C(cellfun('size', C, 1) == 288);
