when using the toolbox.


DASH is a Matlab toolbox designed to facilitate paleoclimate data assimilation. It includes modules to help:

  • Catalogue and organize climate data,
  • Design state vector ensembles,
  • Implement proxy system models, and
  • Run Kalman filter, particle filter, and optimal sensor algorithms.

Install DASH

There are 3 ways to install DASH:

  1. Using Github,
  2. Via MATLAB's Add-On explorer, or
  3. Using MATLAB File Exchange


  1. Navigate to the most recent stable release: Latest Release
  2. Under the release assets, download the file: DASH-<version>.mltbx
  3. Open the downloaded file. This should automatically install the DASH toolbox in your MATLAB environment. (If you previously installed a DASH toolbox using a .mltbx file, this will update your toolbox to the latest version)

MATLAB Add-On Explorer

  1. Click on the Home tab in the MATLAB editor,
  2. Click on the Add-Ons or Get Add-Ons button,
  3. Search for DASH and click on the entry for the toolbox (Its tagline is "A Matlab toolbox for paleoclimate data assimilation")
  4. Click on the Add button in the top-right corner and follow the instructions.

MATLAB File Exchange

  1. Navigate to the submission for the toolbox: DASH on FileExchange
  2. Click the Download button in the top right corner and select the Toolbox option. This should download a file with the name DASH-<version>.mltbx.
  3. Open the downloaded file (its name should follow the pattern DASH-<version>.mltbx). This should automatically install the DASH toolbox in you MATLAB environment.

Getting Started

To get started with the DASH toolbox, enter:

>> dash.doc

in the MATLAB console. This will open the DASH documentation, which includes resources for starting with DASH. In particular, we recommend checking out the DASH tutorial. The tutorial begins with an overview of the DASH toolbox, and then provides step-by-step instructions and examples for using the components of DASH. We recommend budgeting several hours to complete the tutorial.

If you have not yet installed the toolbox, you can find the DASH documentation online here: DASH Documentation

And the tutorial is available here: DASH Tutorial

The following is an overview of the branches of the DASH repository.


This branch holds the most up-to-date source code for the DASH toolbox. This branch is intended for developers rather than users. It may contain active development and may not be stable. If you are looking to use the DASH toolbox, we recommend downloading and opening the DASH-<version>.mltbx file from the most recent stable release.


This branch holds the source code used to implement the online DASH documentation website.
