Suppose your sample variogram (the estimates) are in z.sem,
then non-interactive fitting without recalculating these
estimates is obtained by the following command file:
data(zinc): dummy;
variogram(zinc): 'z.sem' : 10000 Nug() + 140000 Sph(800);
method: semivariogram; # supress interactive mode
set fit = 1; # or whatever fit method you want
It gave me the following output (z.sem obtained from
ex01.cmd):
[edzer@pebesma cmd]$ ../src/gstat z
gstat: Linux version 2.1.1 (January 2000)
