Never heard of it. Do you have a definition of " discreteness "?

it is the summation of all the
absolute differences between any two consecutive bins in a histogram

There is no direct matlab function to do this, but you can code
sum(abs(diff(hist(DATA))))

Of what practical use is that?

Dunno. Seems to me the standard deviation of the absolute differences might be more interesting.
