##Brief summary:
nctoolbox is a Matlab toolbox that provides read-only access to common data model datasets. Under the hood, nctoolbox uses NetCDF-Java as the data access layer. This allows nctoolbox to access NetCDF, OPeNDAP, HDF5, GRIB, GRIB2, HDF4 and many (15+) other file formats and services using the same API. It works with Matlab 2008a and later.
###Prequisites
Matlab R2008a+. You can verify the version of Matlab by typing:
version
Java 6+. You can verify the version of Java used by Matlab by typing:
version('-java').
The version returned should start with 'Java 1.6'. If it starts with 'Java 1.5' you can try updating the Matlab JVM: http://www.mathworks.com/support/solutions/en/data/1-1812J/ or use the older nctoolbox-20091112 version of this toolbox.
###Setup
In Matlab, change to the nctoolbox directory. For example,
cd ~/Documents/MATLAB/nctoolbox
Run the setup_nctoolbox.m function
setup_nctoolbox
This sets up nctoolbox for the current Matlab session only. You will need to add the follwing lines to your startup.m file if you would like nctoolbox automatically when you start Matlab:
% Edit "/Path/to/nctoolbox" to correct nctoolbox directory
addpath("/Path/To/nctoolbox")
setup_nctoolbox
###Demos
- Demos that display basic functionality are in the 'demos' subdirectory. These demos can fail if the machines serving the remote data access URLs are unavailable.
- Contributed demos that display additional or specialized functionality are in the demos/contrib directory. Some of these depend on accessing remote sites for data that can be less reliable than the data URLs in the 'demos' directory.
