EMDtool

Quick start guide

First-time initialization instructions

  1. Contact support (antti (at) smeklab.com) to obtain your licence and download instruction.

  2. Download and unzip the toolbox

  3. Add EMDtool (with all subfolders) to your Matlab path
    • e.g. addpath(genpath('C:/path_to_folder/EMDtool'))
    • or add permanently via startup.m
  4. Activate your license
    • emdtool.load_license('license_file_name.lic')
  5. (OPTIONAL:)(But preferred) Download and unzip the free gmsh mesh generator for your operating system
    • Downloads page
    • Please do recognize that gmsh is a separate software, governed by its own license agreement, only interfaced by EMDtool via a limited-functionality file interfaced
    • If you require other mesh generators, or wish to use EMDtool’s own development-version mesh generator, please enquire via email
  6. (OPTIONAL:) Setup gmsh path, e.g. emdtool.set_gmsh_path('C:/Programs/gmsh/')
    • see help emdtool.set_gmsh_path

Usage instructions

  1. Add EMDtool to your Matlab path (see 3. above)
  2. Analyze away!
    • see Examples/readme.m + example scripts for more detailed examples
    • or, see EMDtool briefly for a brief overview

Downloading a new version?

  1. Download

  2. Unzip

  3. Add the new version to the path.

Indeed, you can easily switch between versions by simply adding and removing versions from the Matlab path. It’s a good idea to call restoredefaultpath and clear classes inbetween, though.

Occasionally, Matlab can be very obstinate about using old implementations of some classes, even if they have been nominally removed from the path. This can be verified by typing open <ClassName> in the command window, to open the class file (or its docfile, in case of .p-files) in the editor, and then checking if its path is old_version/EMDtool/ClassName.m instead of new_version/EMDtool/ClassName.m. Fear not - this is nothing that a good o’ restart (of Matlab) won’t fix.
