This is probably trivial (hopefully): issuing

  a = CreateUmtsInterleaver (100)

I get

  error: `CreateUmtsInterleaver' undefined near line 1 column 5

`CreateUmtsInterleaver' is a oct-file generated, like Capacity
above, with:

  mkoctfile-2.9.10 -o CreateUmtsInterleaver.oct --mex

At a guess I would say that you are not linking to the
interleaver library.

You can use "ldd CreateUmtsInterleaver.oct" to see what
libraries it depends on and "nm CreateUmtsInterleaver.oct"
to see what symbols it is missing.
