Where Can I Find Demo Files for Wavelet Toolbox on a Mac?

I recently downloaded and installed the wavelet toolbox on my mac, and cannot find the demo file noising.mat anywhere. I tried uninstalling and re-installing and still no luck. Could someone please help me find where these files reside? I even did a spotlight search and that file does not exist anywhere on my computer. Is there a way to re-install the demo files, or can I just downloaded the files and place them in my own folder structure?

Thanks in advance, Bryan
