compare a vector with every cells element and get the missing
显示 更早的评论
hi . i have a vector V=[1:100] and a C=cell(1-n) with double[] values . how could i get the values in the vector that are not in any element of cell ? and another question : how could i get a vector with repeats of elements in cell ? for example if there are three 2 in the all elements of cell , in my vector index(2) i have 2 ? thanks a lot !.

Convert C to numeric and use

The second question is basically just a histogram isn't it?

Use setdiff inside cellfun:
V = 1:100;
C = {randi(100, 1, 75)}; % Create ‘C’
Out = cellfun(@setdiff, {V}, C, 'Uni',0); % Use ‘setdiff’
Result = [Out{:}] % Dsiplay Result (Not Necessary For The Code)

It is necessary to use a loop to get separate outputs from each comparison of the elements of ‘C’. (Using repmat with ‘{V}’ fails to do this.)
This should work:
V = 1:100;
C = {randi(100, 1, 75), randi(100, 1, 55)}; % Create ‘C’
for k1 = 1:size(C,2)
Out{k1} = cellfun(@setdiff, {V}, C(k1), 'Uni',0); % Use ‘setdiff’
end
Result = [Out{:}]; % Dsiplay Result (Not Necessary For The Code)
I do not know what size ‘C’ is, so I am assuming it is (1 x n). If it is (n x 1), change the size dimension to ‘size(C,1)’. (You could also use the length function, but without knowing more about ‘C’, I hesitate to suggest it.)

My pleasure.
My code should work with it as written.
