This should work on both char arrays as well as strings:
a = { '1010'
'111'
'010'
'10'
'10111'}
a = 5×1 cell array
{'1010' } {'111' } {'010' } {'10' } {'10111'}
b = pad(a, '0')
b = 5×1 cell array
{'10100'} {'11100'} {'01000'} {'10000'} {'10111'}

a={'1010'
'111'
'010'
'10'
'10111'};
b=char(a)
b = 5×5 char array
'1010 ' '111 ' '010 ' '10 ' '10111'
b(b==' ')='0'
b = 5×5 char array
'10100' '11100' '01000' '10000' '10111'

@Fangjun Jiang gave a great answer for character arrays (which is what you show that you have).
This is a case where MATLAB's new-ish (R2016) string data type might suit your need better, if you can go upstream in your code to use that type.
string = ["1010";
"111";
"010";
"10";
"10111"];
pad(string,"0")
ans = 5×1 string array
"10100" "11100" "01000" "10000" "10111"
