help with nested indexing

Hi, my problem is not difficult but i am getting confused about it. So i have two vectors of indexes Nzlocs and locs

    Nzlocs=[113  664 853  1236 2035];
    locs=[113  202  296  403  546  606  664  812  853  909  999  1099  1189  1236  1278  1366  1460  1546  1595  1634  1722  1809  1896  1987  2035  2072  2159  2246  2333  2422  2498  2590  2674  2760  2854  2939];

and i want to find when this indexes are equal so i can finally locate my needed vector. The problem is that one vector has indexes of the other , for example the value 113 is the 1st so it will be 1 , the 664 7th so 7 etc. I wrote this code but i get an error that i exceed dimensions, note that zeropad is my custom function that performs zeropading to the needed vector so that it have same length as the other. So how can i do it, any ideas? thanks in advice.

    fidx=arrayfun(@find,zeropad(Nzlocs,locs),locs ,'UniformOutput' );

One way

[~,ixb] = ismember( Nzlocs, locs )
ixb =
     1     7     9    14    25

and a way using arrayfun and find

fidx = arrayfun(@(x) find(x==locs), Nzlocs, 'UniformOutput', true );
