In line 2 below, "randi(100)" is returning characters, including black spaces, instead of integers. What code is converting "randi(100)" to return characters above line XXX, and how can I change this code to return integers?
dstr=num2str(d);
name=strcat('d',dstr,'_',randi(100));

IMO: it's better to use sprintf
>> name = sprintf( 'd%s_%d', dstr, randi(100) )
name =
dhello_91

I think you might want
name=strcat('d',dstr,'_',num2str(randi(100)));
This will convert the number to its string equivalent, rather than the ASCII value corresponding to that value (which is what I assume is happening now).

Thanks for the quick reply, Cyclist. That did the trick. Very green here, so it's much appreciated.
