[OctDev] Hi all, and a first question about graycomatrix

[<gio...@un...>]

Hi all,
first message to the list for me!
I am new to octave and octave forge, but I'm a (quite) expert matlab
programmer. I am going to translate to octave, and to its packages, some
tools I wrote in the field of medical image processing.
My first question, hoping this is the right place to ask, concerns
graycomatrix: I am trying to understand what its parameters are, because
it is quite different from matlab equivalent function. While I imagine
that distances are just what the word says, an array of distances between
pixels, I do not understand how angles are given.

Stefan van der Walt (after submitting this function many years ago) said
"try the demos": can someone suggest me where they are?
Thank you very much!
Best regards
Giorgio
