Hello, are the contents of cell 2 column 2 just repetitions of the contents of cell 1 column 1??

Nikhil Negi yes repetitions and some other extra things which do not exist in the cell1 column and i just focused on the common contents.

So you can say all the content of cell1 column1 exist on cell2 column2 with repetitions

Hello chocho,

you can use temp=ismember(cell1,cell2(:,2)) ans=all(temp); if ans=1 then cell1 is a subset of cell2 column 2(your required condition) and if ans=0 then your condition is not satisfied
