Use a cell array of strings for b and use logical indexing instead of a.*b,
>> b={'ben';'james';'mike';'ralph';'will'};
>> a=logical([1;0;1;1;0]);
>> b(a)
ans =
'ben'
'mike'
'ralph'

Speaking of mathematical operations with strings, ever wonder what you get when you cross a cat with an owl?
>> cross('cat','owl')
ans =
-3328 2184 1014
