1. Download and unpack
   Download the EasySpin zip file and unpack it to a folder, e.g., C:\ or /var/myfiles/. Once unpacked, EasySpin is contained in a subfolder of C:\ (or /var/myfiles/ or whatever directory you chose) which in turn contains various subfolders:
   • easyspin - all the toolbox functions.
   • documentation - documentation in HTML format, entry point is index.html.
   • examples - all examples, grouped into subdirectories.
2. Add to MATLAB path
   Launch MATLAB and go to menu File → Set Path... Remove any folders containing older EasySpin installations from the MATLAB search path. Add the EasySpin subfolder easyspin to the MATLAB search path by clicking on "Add Folder...", selecting the easyspin subfolder in your EasySpin directory, and clicking on "Save".
3. Compile
   Type easyspin at the MATLAB command prompt. Possibly you are asked to select a C compiler. In that case, choose Lcc (Windows) or gcc (Linux, OSX). The final output in the command window should look like
