So, there are two different tcpclient type of objects: one corresponding to the stand-alone Matlab installation and one implemented by the addition of the Instrument Control Toolbox:

https://ch.mathworks.com/help/releases/R2026a/instrument/tcpclient.html

They are not really the same, for example the one from the Instrument Control Toolbox has the writeread method, whereas the other does not.

What I find weird is that on a matlab installation without the Instrument Control Toolbox installed, I can still use the writeread method of the object (and it works as expected!).

How can this be?!?

Admittedly, I did have the Instrument Control Toolbox installed on the machine (but I uninstalled it due to other reasons). Yet, I would have expected the writeread method not to be recognized anymore, after the removal of the toolbox.
