matlab.io.hdfeos.gd
Low-level access to HDF-EOS grid data
Description
To use these MATLAB® functions, you must be familiar with the HDF-EOS library C
interface. In most cases, the syntax of the MATLAB function is similar to the syntax of the corresponding HDF-EOS
library function. The functions are implemented as the namespace
matlab.io.hdfeos.gd. To use this namespace,
prefix the function name with a namespace path, or use the import function
to add the namespace to the current import list, prior to calling the
function, for example,
import matlab.io.hdfeos.* gfid = gd.open(filename,'read');
