Hi, I had a code working in the 7.8.0 (R2009a) Release. Now - working under R2011b - I got the following error: "Undefined function 's2y' for input arguments of type 'double'."

Since I copied the s2y-function manually from old to new version, also tried the example provided at the MathWorks Page and still got the same error I'm suspecting something changed with the Versions interpretation of the function?

As the "s2y" function seems to belong to the RF Toolbox I checked the Release Notes and see if I can find something - but that didn't help a lot either.

I don't know where else to look, any ideas would be appreciated.

Best Regards

Please contact Mathworks, because it looks like an issue with your obtained license.

Sorry, did you write somewhere besides this topic? I didn't see it.

Ja, das war eine Privatnachricht - aber es ist ja gelöst.

I suggest to check if RF Toolbox is installed in your matlab version.

Hope it helps!!!

Thanks, yes I checked by asking matlab "ver" and it wasn't listed. I then started the installation of 2011b matlab again and chose "Custom Installation" to check if RFSim is installed/re-install. But it is not listed there. So could this be a problem with the version or with our obtained license?

Thanks for your help!, I figured it out: it really was because of the licences. Obviously they recently changed. The code worked after I copied not only s2y.m but also CheckNetworkData.m manually.
