(patch area distribution coefficient of variation) calculates
as:
with:

MPS: mean patch area size
ai: area of patch i

EXAMPLES
To calculate mean pixel attribute index on map my_map, using
my_conf configuration file and saving results in
my_out file run:
r.li.padcv map=my_map conf=my_conf output=my_out
NOTES
Do not use absolute path names for output files. They are raster if
moving window disposition was selected, otherwise they are in
~/.r.li/output folder.
If input raster is not full of null values r.li.padcv returns a value >=0 that is PADcv.
If input raster is full of null values r.li.padcv returns -1.
If you want to have null values instead run
