Interact directly with NetCDF Library
Functions in the MATLAB® netcdf package
provide interfaces to dozens of functions in the NetCDF library. The MATLAB functions
enable reading data from and writing data to NetCDF files (known as data
sets in NetCDF terminology). To use these functions, you
should be familiar with the NetCDF C Interface.
MATLAB supports NetCDF version 4.3.3.1.
In most cases, the syntax of the MATLAB function matches
the syntax of the NetCDF library function. The functions are implemented
as a package called netcdf. To use these functions,
prefix the function name with the package name, netcdf.
For example, to call the NetCDF library routine used to open existing
NetCDF files, use the following MATLAB syntax:
ncid = netcdf.open(ncfile,mode);
