EasySpin comes in a single zip file, containing all toolbox functions and the full documentation.

Visit the EasySpin website for downloading the latest version.

EasySpin requires MATLAB 7.0 (R14) or later on either Windows, Linux or Mac. Beyond a basic MATLAB installation, no additional MATLAB toolboxes are needed to run EasySpin.

1. Download and install support software
   A small but critical part of EasySpin is not written in MATLAB, but in C. In order to compile and run this part, some support software has to be installed, depending on the platform.
   • Mac OS X: Download and install Xcode 3 (not Xcode 4).
   • 64-bit Windows: Download and install Microsoft Visual C++ 2010 Redistributable Package (x64).
   • 32-bit Windows or Linux: Skip this step.
2. Download and unpack EasySpin
   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, entry point is index.html.
   • examples - all examples, grouped into subdirectories.
3. Tell MATLAB about EasySpin
   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".
4. Compile EasySpin
   In MATLAB, type easyspin at the command prompt. Possibly you are asked to select a C compiler. In that case, choose Lcc (Windows 32bit) or gcc (Linux, Mac). The final output in the command window should look like
