Let's say I have two arrays:

 A = {'one(1)', 'two(1)', 'three(2)', 'four(2)', 'five(1)'};
 B = {'One', 'TWo', 'thrEE', 'Four', 'fiVe'};

I need to know the indices in the array A that have a: (1) and in the array B only one capital letter. For this example the indices are:

idx = [1, 5]

Could you recommend me something using cellfun or something else without loops or ifs?

Thanks in advance

IndA=contains(A,'(1)');
IndB=cellfun(@(x) sum(x)==1, isstrprop(B,'upper'));
Index=find(and(IndA,IndB))
