Concatenate Cell Arrays (string and numeric)

Hi all, I have two cell arrays: tempName & tempWeightSTR. 1. tempName was populated with strings. 2. tempWeightSTR started out as tempWeight which was numeric and I used num2cell to convert it to a cell array.

Is there a way to concatenate the two arrays so the resulting elements look like: ['Paul (20%)', 'John (24%)', 'Ringo (5%)']

I need my results to be one vector, i.e. ['A(1%)','B(2%)','C(3%)']... not [ 'A', 'B', 'C' '1%', '2%', '3%']

I tried strcat(tempName,' (', tempWeightSTR,')') but the numeric values do not show up for some reason.

Also, can someone please point me in the right direction to format the numeric values to string percentages (%)?

Thanks in advance! jason

a={'john','harry'};
b={'20','30'};
s='%'
for i=1:2
    bb=cell2mat(b(1,i));
    str=sprintf('(%s%s)',bb,s);
    a(1,i)=strcat(a(1,i),str);
end

Thanks Nirmal, 2 things.

1. Using the expression below the ans is 3.300000e-002%. I need 3.3%. sprintf('(%s%s)', 0.033,'%')

2. Is there a way to do all of this without a loop? I'd prefer a single expression.

Either way, thank you very much for your help! jason

I figured out #1 '%0.2f%s' = 3.30%

However, I'd still like to avoid using a loop. Thanks! jason

a={'john','harry'};
b={'20','30'};

a=strcat(a,'(',b,'%)');
