I have a cell array of up to hundreds of elements say A = cell(1,100). Each cell has a variety of three-column vectors (all 3-columns but could vary in number of rows): A{1} = [1 2 3; 4 5 6; 7 8 9]; etc.
Is there a way to use the built-in functions to see if the vector [1 2 3] exist in A?

A{1}= [1 2 3; 4 5 6; 7 8 9];
A{2}= [11 2 3; 4 5 6];
A{3}= [1 12 3];
IsInA=any(cellfun(@(x) ismember([1 2 3], x,'rows'),A))

Thanks! I have used similar clauses before but never really understood how it works. What is the meaning of @(x)?
