[GRASS-user] v.surf.rst error: Input window change

[Daniel Victoria]

As an update, if I remove the mask raster option, the interpolation
finishes ok but it gives me the message at the end...

G_ludcmp() failed! n=0  d=0.00
G_ludcmp() failed! n=0  d=0.00
G_ludcmp() failed! n=0  d=0.00
v.surf.rst complete.

Cheers
Daniel
