Download and Installation Instructions.
[Note: 32-bit modules are no longer supported.]

Windows:

   Download the following compressed file: 
       64-bit Windows: matlab_cdf_win64.zip
   Double-click the downloaded file to extract the files included 
       in the package to a directory (default to matlab_cdf392_win64).
   Download leap second table: CDFLeapSeconds.txt and set the environment
       variable CDF_LEAPSECONDSTABLE to the downloaded leap second
       table. The step is only necessary when a new leap second is added and
       the shared library is not upgraded through the previous step. This
       environment variable needs to be set when running CDF modules under
       MATLAB. 
         set CDF_LEAPSECONDSTABLE=<...>\CDFLeapSeconds.txt
            where <...> is the directory that holds CDFLeapSeconds.txt
   Invoke MATLAB and issue the following command at the MATLAB prompt:
        addpath '<patch_install_dir>'
        For example, if the patch is installed under
        C:\users\jones\my_matlab\matlab_cdf392_win64, the command should be
          addpath 'C:\users\jones\my_matlab\matlab_cdf392_win64'
   Use MATLAB as usual (e.g. data=spdfcdfread('test.cdf')).

Mac OS X:

   Download one of the following compressed tar files:
       matlab_cdf_maci64.tar.gz - for Mac OS X running MATLAB R2023a and earlier
       matlab_cdf_maca64.tar.gz - for Mac OS X running MATLAB R2023b and later
   Move the downloaded file into the directory you want the patch to be
   installed. Extract the files in the package using the following command:
        tar zxvf <downloaded compressed tar file>
     [The extracted files will be placed in matlab_cdf392_patch-64 directory.]
   Download leap second table: CDFLeapSeconds.txt and set the environment
       variable CDF_LEAPSECONDSTABLE to the downloaded leap second
       table. The step is only necessary when a new leap second is added and
       the shared library is not upgraded through the previous step. This
       environment variable needs to be set when running CDF modules under
       MATLAB. 
         setenv CDF_LEAPSECONDSTABLE <...>/CDFLeapSeconds.txt (C/TCsh)
         export CDF_LEAPSECONDSTABLE=<...>/CDFLeapSeconds.txt (Bourne/Bash)
            where <...> is the directory that holds CDFLeapSeconds.txt
   Invoke MATLAB and issue the following command at the MATLAB prompt:
        addpath '<patch_install_dir>' 
        For example, if the patch is installed under /Users/jones, the 
        command should be
          addpath '/Users/jones/matlab_cdf392_patch-64'
   Use MATLAB as usual (e.g. data=spdfcdfread('test.cdf')).

Linux

   Download the following compressed tar file:
       Linux 64-bit: matlab_cdf_lin64.tar.gz
   Go to the directory where you want the patch to be installed under.
   Extract the files in the package using the following command:
       tar zxvf <downloaded compressed tar file> 
     [The extracted files will be placed in matlab_cdf392_patch-64 directory.]
   Download leap second table: CDFLeapSeconds.txt and set the environment
       variable CDF_LEAPSECONDSTABLE to the downloaded leap second 
       table. The step is only necessary when a new leap second is added and
       the shared library is not upgraded through the previous step. This
       environment variable needs to be set before running CDF modules under
       MATLAB.
         setenv CDF_LEAPSECONDSTABLE <...>/CDFLeapSeconds.txt (C/TCsh)
         export CDF_LEAPSECONDSTABLE=<...>/CDFLeapSeconds.txt (Bourne/Bash)
            where <...> is the directory that holds CDFLeapSeconds.txt
   Invoke MATLAB and issue the following command at the MATLAB prompt:
        addpath '<patch_install_dir>'
        For example, if the patch is installed under /Users/jones, the
        command should be
          addpath '/home/jones/matlab_cdf392_patch-64'
   Use MATLAB as usual (e.g. data=spdfcdfread('test.cdf')).
