Hash Function

[Jonathan Karsch]

Hello,

I am trying to figure out how many distinct words are in a text document, and 
how many instances there are of each.
I was wondering if there is a way to create a hash table in Octave after I have 
read in the document line-by-line. I would also need to go through with 
something like myhash(%word) =+1 so it can hash each word.

Thank you,
Jonathan
