Details:

I've noticed that Octave's nchoosek function requires the first input to be a
scalar or a numeric vector. In Matlab it can be a char vector (i.e. string) or
a row cell array. I think this is good because it extends functionality.

It's very easy to generalize Octave's `unique` to do this, using a workaround:
call builtin `unique` with a numeric vector and then use the result that to
index into the original input. I'm attaching my workaround function.
