Hi,
Gstat terminates with the message "matrix library error: singular
matrix" (see below). I have observations at identical locations. But
they are averaged by the "average" option in the .cmd file. Maybe an
observation falls almost exactly at a simulation location. I do not
understand exactly what is meant by increasing the value of zero. Does
it mean the origin of the coordinate system?
Are there any other possible solution apart from the manual to overcome
a singular matrix in conditional simulation?

gstat caught an error that occurred in the matrix library,
the reason for it was: singular matrix
HINT: Read the manual (http://www.geog.uu.nl/gstat/manual)
