matlab.io.hdfeos.sw

Low-level access to HDF-EOS swath files

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.sw. 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.*
fileId = sw.open(filename);
