Hello,

I updated my MATLAB from 2015a to 2017a recently. However in 2017a I can't connect to my hardware instrument through GPIB. I get the following error message:

"Error using gpib (line 147) Unable to load AGILENT GPIB interface. Please check that the necessary drivers are installed on your machine. Error in createInst (line 8) INST = gpib('AGILENT', board, Addr); "

Any ideas on how I can fix it? It's still working in the 2015a-version.

Br Aleksander

Hello,

Driver requirements for Agilent GPIB drivers changed from MATLAB R2015a to R2017a http://www.mathworks.com/help/releases/R2017a/instrument/driver-requirements.html http://www.mathworks.com/help/releases/R2015a/instrument/driver-requirements.html

Please install the support package "Instrument Control Toolbox Support Package for Keysight IO Libraries and VISA Interface" in MATLAB R2017a which will install the appropriate drivers.
