If you have only positive integers, you can use an undocumented feature of strfind:
D=[0 1 1 2 3 4];d=[1 2 3];
strfind(D,d) % returns 3
If you have also other values, you can use third output of unique to convert your values into positive integers. If you're using GNU Octave you will have to cast to char to make this work (in which case only 0-255 values are likely to work).
