This function generates a hash value from a text string
hash=string2hash(str,type);
inputs,
str : The text string, or array with text strings.
outputs,
hash : The hash value, integer value between 0 and 2^32-1
type : Type of has 'djb2' (default) or 'sdbm'
From c-code on : http://www.cse.yorku.ca/~oz/hash.html
djb2
this algorithm was first reported by dan bernstein many years ago
in comp.lang.c
sdbm
this algorithm was created for sdbm (a public-domain reimplementation of
ndbm) database library. it was found to do well in scrambling bits,
causing better distribution of the keys and fewer splits. it also happens
to be a good general hashing function with good distribution.
example,
hash=string2hash('hello world');
disp(hash);
