MATLAB: How to find prefix and postfix in a recursive way

C = {'23414','342(1)','34','231'};
pfx = cellfun(@(s)regexp(s,'\d','match'),C,'UniformOutput',false);
fun = @(s)arrayfun(@(n)s(n:end),regexp(s,'(\d|\(\d\))'),'UniformOutput',false);
sfx = cellfun(fun,C,'UniformOutput',false);

and the two output cell arrays contain:

>> pfx{:}
ans = 
    '2'    '3'    '4'    '1'    '4'
ans = 
    '3'    '4'    '2'    '1'
ans = 
    '3'    '4'
ans = 
    '2'    '3'    '1'
>> sfx{:}
ans = 
    '23414'    '3414'    '414'    '14'    '4'
ans = 
    '342(1)'    '42(1)'    '2(1)'    '(1)'
ans = 
    '34'    '4'
ans = 
    '231'    '31'    '1'
