I cannot load "quadchirp" because file not found. I tried some other defaul data files such as sunspot.dat and it works. Where is this quadchirp file?

If you listed the entire result from running the ver function, it seems that you do not have the Wavelet Toolbox.

I’m not certain how institutional licenses work, since I never used MATLAB as part of one.
Your best option is to ask the license administrator how to download and install the Wavelet Toolbox.
Wavelets are interesting and quite useful, so you’ll enjoy exploring them!
