How do I interpolate a geolocated data grid (generalized matrix map) to produce a regular data grid (regular matrix map) using the Mapping Toolbox?

I have a geolocated data grid (lat, lon, and z arrays with irregular spacing) that I would like to convert into a matrix of values having uniform cell spacing. I would like to interpolate this data into a regular data grid.

To interpolate a geolocated data grid (generalized matrix map) into a regular data grid (regular matrix map) with uniform spacing, use the GEOLOC2GRID function from Mapping Toolbox 2.0.

For earlier versions of the Mapping Toolbox, you can use the attached GRIDMAP function. Download the attached version of the function, and place it on the MATLAB path.
