Thanks Mike!

I would want you to clarify on this, as of now as I see I don't find
anything about categorical data type in octave source.
Does it mean I got to implement the whole datatype and its related
functions. I think to provide support for a new datatype, many of the
preexisting functions need to be modified too.

I want to know weather I am right or not? If yes, then this project becomes
very big, so please suggest me the starting point or the starting function I
should start developing upon. 

Thank you,
NVS
