Question

AccuSumNet({'123456789101112131415161718192021222324252627282930' '123456789101112131415161718192021222324252627282930123456789101112131415161718192021222324252627282930' '12345'});
function x=AccuSumNet(:,n)
y=x-'0';
sum(y);
AccuSumNet(:,n+1);
end

Answer 1

function x=AccuSumNet(n)
  for k=1:length(n)
    x(k)=sum(n{k}-'0');
  end
