Matlab functions for writing and reading grids

I have found that grid formats in many software products are difficult to use. Here are some functions to help.

These functions to read and write single or multidimensional gird typically used in geophysical work, but are useful in general. The grids are in a non-propietary GGG format. The full description is in the README.PDF, RTF or TXT files. The functions are:

function Params = gg_grdinfo(filnm);

function gg_wtgrd(filnm, G, X, Y, Z, Params);

function [G, X, Y, Z, Parms] = gg_rdgrd(filnm, lg_info);

Test data and programs, I/O grids, and statistical analysis are included.
