count number of index in many vector

if i have

A{1} = 2
       8
       1
       1

then the solution will be 4

A{2} = 1
       3
       5
       4
       5
       2

then the solution will be 6

A{3} = 4 5 3 2 5 3 1

then the solution will be 7

i need this solution for A{k}

I hope this is what you want..

I assume k=4 and made A{4} with 14 numbers and expected so expected solution is 14.

k=4;

A=[];

A{1}=[2;8;1;1] ;

A{2}=[1;3;5;4;5;2];

A{3} = [4,5,3,2,5,3,1];

A{4}=[4,5,3,2,5,3,1,4,5,3,2,5,3,1];

S=zeros(1,k);

for i=1:k

s=(size(A{i}));

S(1,i)=max(s);

end

S
