why 'getnameidx' does not work?

i have two list of names

a = {'a1301013717010201102.csv';
'a1301013717010201103.csv';
'a1301013717010201104.csv';
'a1301013717010201105.csv';
'a1301013717010201106.csv';
'a1301013717010202101.csv';
'a1301013717010202102.csv'};
and 
b = {'a1301013717010201102.csv';
'a1301013717010201103.csv';
'a1301013717010201104.csv';
'a1301013717010201105.csv'}

i used nameidx = getnameidx(a,b); but it cant find would u help me?

"getnameidx will be removed in a future release. Use contains instead..."

I don't have the Financial TB to test but seems to be a superfluous function

>> find(contains(a,b))
ans =
   1
   2
   3
   4

amongst other ways.
