Hi, I found the 'envelope' function described in http://www.mathworks.com/help/signal/ref/envelope.html very useful for my project, the document says this function is included in R2015b, but I can't run the example code with this function (the chirp function also not working with my R2015b). By the way, I am using an academic license. Can anyone make clear how can I use this function? Thank you!

I have this function in my installation
>> which envelope
C:\Program Files\MATLAB\R2015b\toolbox\signal\signal\envelope.m
Path suggests it is part of the Signal Processing Toolbox. Can you run "ver" to verify you have it installed? It should look like

I see you should have access to a university license including that product.

Hello,I have installed the signal processing toolbox but the function envelope is not found. I have MATLAB 2015a academic license. Is the function not found in this version of MATLAB?

The note at the bottom of the documentation page indicates it was "Introduced in R2015b", the release after the one you're using.
