Downloading CDT

You have a few options for downloading CDT. You can get the most recent release of the toolbox here (about 100 MB) and just double-click on the file to install it (described below) or you can find all the latest individual files through the Add-Ons menu (Method 2 described below), on the Mathworks File Exhange or on GitHub.

Installing CDT in Matlab

You have two options for how to install CDT:

1. If you have already downloaded the .mltbx file, navigate to it in your file system and it might look something like this:

Just double-click on that file and when the menu pops up, click Install. Installation should take less than a second.

2. Alternatively, if you haven't already downloaded the mltbx file, you can get it via the Add-On button from directly within Matlab. That looks like this in the HOME menu:

Click Get Add-Ons, look up Climate Data Toolbox, and follow the prompts to download and install CDT automatically.

Accessing Help
