Hello,
You can try out the Higher Order Statistical Analysis (HOSA) Toolbox developed
by Ananthram Swami. Therein you can find a function named 'bicoher' to
estimate the third order moment of a given signal.

Hi does anyone know how to compute bicoherence of a signal. I need it for
nonlinearity check of the system that produce it. there are some MATLAB codes in
the web for example in the:

tion/bicoherence .m
but I donot know how I should use them.
Thank you very much!
