Anybody else having issues getting the 'Hosa Demo' to work? It tells me
'Undefined function 'choices' for input arguments of type 'char'. Granted, I can go into the folder and open any demo I need, but I'm not really sure what they all are.

Second question (and maybe I just need to read on this), but how does the window work? From the demo, it seemed he chose an arbitrary size? I'm looking to calculate the bi-spectrum. I'm used to making my own hanning window when I do a regular FFT; this appears to be different.

Also, to remove the annoyance of inexact case matches when you use the any of the HOSA functions, I'd recommend putting this line of code at the top of your script:

warning('off','MATLAB:dispatcher:InexactCaseMatch').

For some strange reason, all of the HOSA function file names are written in all caps.
