MATLAB: Logical indexing in cell array

cell arraysMATLAB

Is there a way to search strings in a cell array similar to numeric arrays?
    a = [1 2 3 4 5 6];
    >> idx = find(a==3)
    idx = 3
    >> b = {'1' '2' '3' '4' '5' '6'};
    >> idx = find(b=='3')
    Undefined function 'eq' for input arguments of type 'cell'.

Use ismember to search cell arrays:
b = {'1' '2' '3' '4' '5' '6'};
logicalIndex = ismember(b, '3')  % Or...
actualIndex = find(ismember(b, '3'))
