Hi, I have installed MATLAB in two different paths inside my Ubuntu 16.04 system. First is : /usr/local/R2017b Second is : /opt/MATLAB/R2017b In the first one when I run lrwpanEndToEndPHYExample.m, it runs properly but when I run the same in second, it throws this error : Undefined variable "lrwpan" or class "lrwpan.PHYGeneratorOQPSK". What I am missing here ? Regards Sumit

Communications System Toolbox Library for the ZigBee Protocol"

Yes I have Communications System Toolbox already installed.

Yes, but you do not have "Communications System Toolbox Library for the ZigBee Protocol" installed.

Go into Add-On Explorer and search for Zigbee. For me it was the first entry.

I think the package you mentioned is already installed. I have attached the screenshot. Regards Sumit

在 MATLAB Online 中打开

It might somehow not be on your MATLAB path. Try

restoredefaultpath

I saw exactly the message you did until I installed the zigbee package, after which I had no difficulty executing the example.

I am very sorry, it was a mistake. When you asked me to check "Communications System Toolbox Library for the ZigBee Protocol", I checked it in the first path where it was already working and not the second path. So indeed for the second path MATLAB installation, the mentioned package was not installed. After installing it, it works! Thank you very much Sumit

As of R2023b, the content in the Communications Toolbox™ Library for ZigBee® and UWB has been absorbed into Communications Toolbox. With that release or later, you no longer need to download the library.
