How to use examples?

After I copy the "openExample('wlan/DMGSCLinkWithRFBeamformingExample')" onto the Matlab, I cannot find the example. the error is

"Wrongly used findExample (line 35)

Cannot find "HTLinkModelWLANExample" in "D:\Matlab2018b\examples\wlan\examples.xml".

Error: openExample (line 24)

metadata = findExample(id);"

Do you have the WLAN Toolbox installed and a valid license for it?

[Qinghe Gao]

Yes，I have installed the WLAN Toolbox 2018b

The problem is solved: the examples shown in Website for the WLAN Toolbox are suppoted by R2019a, but what I installed is R2018b.

There is possible that you don't install the correct version of the matlab. try to search by the name of that example if there is available in the demo matlab file.
