Installation

• Download files 1.-4. + some test data (see above) and and copy them into one single directory, for example into a directory mat2dcos.
• Add then this directory to Matlab's search path. For this start Matlab and type
  

   >> addpath('Mat2DcorrPath')

at the Matlab command prompt, where Mat2DcorrPath denotes the full path where the the toolbox resides (i.e. mat2dcos).
Example of Mat2DcorrPath: C:\Users\Tim\Documents\Matlab\mat2dcos

• To start mat2Dcorr type
  

   >> mat2dcorr

at the Matlab prompt.

This will open two different windows:

1. A window entitled '2D correlation analysis ... ' which shows the 2D correlation spectrum and mean spectra obtained from the x- and y-spectral data
2. The 2D-COS control window, the user dialog box, see screenshot below
