[GRASSLIST:3560] Re: Geophysical framework: WHITE PAPER

[Paul Kelly]

Hello Michael,
This was a very interesting discussion and taught me something about 
some aspects of GRASS functionality that I have used other software 
(mostly MATLAB) to achieve up to now. I've made two comments below:

r.digit is fairly useful for this

Not exactly---the same source code is now used for generating the 2-D 
and 3-D versions of mapcalc but the latter is still a separate module 
(r3.mapcalc)

Hope this adds some clarification.
