Here you can download the GPELab toolbox.

Installation of GPELab

To install GPELab, you only have to unzip the zip file. Then, add the GPELab directory and its subdirectories in the Matlab setpath menu. You can launch Matlab which now has the correct paths for using the GPELab functions. Once its done, GPELab can be directly used. You can open any of the examples files (for instance in GPELab/Code 1D/Examples) and test it to check that everything works correctly.
