I am trying to use the tcpserver() function to ser up a tcp/IP server on my computer. It runs on the 'Instrument Control Toolbox' and I have confirmed I have it installed because it shows up on my 'Add-Ons Manager'. However, when I try to call the function or even type 'help tcpserver' Matlab throws the error "Unrecognized Function or Variable 'tcpserver'." Any ideas what I am doing wrong or how to fix this?

在 MATLAB Online 中打开

What do you get from this?

v = ver;
any(contains(lower({v.Name}), lower('Instrument Control Toolbox')))
ans = logical

I appreciate your response Ive, but I just realized that teh function, tcpserver, is a new function to MATLAB 2021 and I only had 2020 verison. Thanks for the help anyway.
