How to use:

1. Download MATLAB files from here.
2. In MATLAB, navigate to the folder where the files are stored 
3. Type gui_xcorr and hit Enter. 

Acceptable formats as input discrete-time signals:

• An array, such as [3, 2, 1, 5] or cos(2*pi*0.02*(0:99))]
• A 2-row matrix with the top row storing sample indices and the bottom row storing sample data, such as [0:3; 3 2 1 5] or [0:99; cos(2*pi*0.02*(0:99))]
