Installation and Quick Start



If you have not yet installed version R2017a of the toolbox, follow steps #1 thru #4. If you have already installed version R2017a but are upgrading to a new license (e.g., a full license instead of a trial license), only step #4 is needed.

  1. DOWNLOAD THE TOOLBOX. This is the .mltbx file. Choose a directory for the file. For example, on a Windows machine one might choose C:\myHomeDirectory\matlab\3rd_party\davinci_draw\R2017a. On a Unix machine one might choose /home/myUserName/matlab/3rd_party/davinci_draw/R2017a.
  2. UNINSTALL PREVIOUS VERSION. This will help avoid name conflicts. Select "Manage Add-Ons" in Matlab to uninstall any previous versions of DaVinci Draw.
  3. INSTALL THE TOOLBOX. In Matlab, switch to the directory with the .mltbx file. (One way is to click the Browse for folder icon on the Matlab GUI and surf to the appropriate directory. Another way is to use the Matlab cd command on the Matlab command line.) The .mltbx file should appear in Matlab's Current Folder browser. Double-click on the .mltbx file. Then click "Install". Matlab will extract the toolbox files, adjust your Matlab path, and integrate the DaVinci Draw toolbox documentation with the main Matlab documentation.
  4. INSTALL THE LICENSE FILE. Download from our website your license file, named davinci_license.txt, and place the file somewhere on your Matlab path. One possibility is to place davinci_license.txt in the same directory you placed the .mltbx file, and add this directory to the Matlab path. (One way to adjust the Matlab path is to click the Set Path button on the Home tab of the Matlab GUI.)

Generate a Drawing

davinci( 'arrow', 'X', [0 10], 'Y', [0 0] );    % Draw an arrow.
daspect( [1 1 1] )   % Set the aspect ratio at 1:1.
