I recently installed RTL-SDR under Simulink. While the support package works fine on one of my computers, I keep on getting error messages on a second install:
Error while obtaining sizes from MEX S-function 'sdrrsfunrx' in 'sdrrSpectralAnalysisExample/RTL-SDR Receiver/sdrrsfunrx'.
Invalid MEX-file 'C:\MATLAB\SupportPackages\R2014a\sdrr\sdrrmex\sdrrsfunrx.mexw64': The specified module could not be found. Component: Simulink | Category: Block error
The checked and ensured that the mentioned file 'C:\MATLAB\SupportPackages\R2014a\sdrr\sdrrmex\sdrrsfunrx.mexw64' is installed on the system.
I also reinstalled the Zadig driver for the RTL-SDR and verified that it is working by running the dongle with SDRSharp.
Anything else that I should try?
Thanks in advance, Arne

Ken,
Thanks for your answer. I managed to resolve my problem:
The USB driver for the RTL-SDR was installed incorrectly. After completely de-installing and re-installing, it now works.
It was somewhat confusing, because SDRSharp was able to communicate with the SDR while Simulink was not.

I have the same problem with you, but my de-installing and re-installing of the driver doesn't work........

Install Depenency Walker and then open the .mexe64 file with it. There many be a dependency that is missing or not on your search path.
Here are some other troubleshoot options.
