find values in vector present in cell array
Show older comments
i have a cell array cA and vector V with values
cA = {[11,21,3;14,5,63], [11,22], [33;95;66;7]};
V = [14 22 33 66];
i wanted to find which all values in V are there in cA and its position
output = { [ 0 0 0 1 0 0], [1 2], [3 0 4 0] }

Dear, Always use matrix instead of cell arrays, working with matrix is really easy as compared to cell arrays. In the code below, i have split cA matrix into three small matrices and then checked the entities which are present in vector V. Afterwards compile the entire output matrix.
%%Splitting cA matrix into three consistent matrices
cA1 = [11,21,3;14,5,63]
cA2 = [11,22]
cA3 = [33;95;66;7]
V = [14 22 33 66];
%%Checking for entities of cA1
[Lia,Locb1] = ismember(cA1,V)
reshape(Locb1,1,[])
transpose(Locb1)
Locb1.'
Locb1(:)
Locb1=reshape(Locb1.',1,[])
%%Checking for entities of cA2
[Lia,Locb2] = ismember(cA2,V)
Locb2=reshape(Locb2,1,[])
%%Checking for entities of cA3
[Lia,Locb3] = ismember(cA3,V)
Locb3=reshape(Locb3,1,[])
Output=cell2mat({Locb1,Locb2,Locb3})

I am unable to understand [11 22 3;44] in cA = {[11,22,3;44], [14,22]};
Its dimensions should be consistent
