Installation

This toolbox does not require running any installation scripts, but you will need to download the surface velocity data and you'll need to make sure Matlab can find the data and these functions.

1. Download the data: Get the data from here: https://nsidc.org/data/NSIDC-0484. It's a file called antarctica_ice_velocity_450m_v2.nc.

2. Add a path to the data and toolboxes: Different distributions of Matlab have different ways of telling Matlab where to look for files. There's one way to do it that works on all versions of Matlab, but it requres a couple of steps: First, put all your AMT files into a directory, for me the filepath is '/Users/chadgreene/Documents/MATLAB/AMT' and in the AMT folder I have many subfolders with all the different AMT plugins. To tell Matlab that it should always look in the AMT folder for data and functions, create, go to your MATLAB directory and create a file called startup.m. It must be called startup.m, no other name will work, and it must be in the MATLAB folder. In the startup.m file write a line like this:

addpath(genpath('/Users/chadgreene/Documents/MATLAB/AMT'));

But of course you'll want to make sure you change the filepath to match your own file structure.
