getgrd2

Read a Geosoft 2-byte binary grid.

Read the old Geosoft 2-byte (signed integer) binary grids. Optionally return the X- and Y- coordinate axes, as well as the dummy value.

Notes:

1. After imaging, remember to set(gca,'YDir','normal'); so image and axes are correct. Or just D=flipud(D); if coordinates are not required.

2. If reading from Geosoft Oasis, first re-save grid as "Geosoft short" type.
