I found a CDMA2000 physical layer demo under communications toolbox in the SIMULINK HELP menu. I have saved the file in MATLAB R2010a version and got the output when simulated. The same file when I tried to simulate in R2010b version, it showed me an error stating that " unable to locate 'mexopts.bat' and therfore cannot determine which compiler to use for simulation builds."
Can some one help me out on why I am unable to simulate it in R2010b version?
