Cross validation

[Poizot Emmanuel <poizot@cnam.fr>]

Hi all,
I tried to do a cross validation of a gaussian simulation.
I put xvalid = 1 in the command file, but always get this :

[using conditional gaussian simulation]

"chfactor.c", line 130: singular matrix in function LDLfactor()

gstat caught an error that occurred in the matrix library,
the reason for it was: singular matrix

HINT: Read the manual at http://www.gstat.org/ ;
look for: Trouble shooting -> Error messages -> From meschach

gstat: matrix library error: singular matrix

I did have a look to the documentation and tried the solutions explained there 
but with no success.
Does anybody have an idear ?
