Warning: Xcode appears to be installed, but it has not been configured. Run "osascript -e 'do shell script "xcode-select -switch /Applications/Xcode.app" with administrator privileges'" to configure Xcode. You must be an administrator of this computer to complete this action.
No supported compiler or SDK was found. For options, visit http://www.mathworks.com/support/compilers/R2014b/maci64.html. gmake: * [solar_module8_sfun.o] Error 255 Component: Make | Category: Make error

Start up the Terminal application, which you can find in /Applications/Utilities . When you get to the command prompt, command
sudo xcode-select -switch /Applications/Xcode.app
and authenticate when it prompts you for your password.
After that xcode will be selected and you should be able to proceed.
Note: be sure that the files have been edited as described in http://uk.mathworks.com/matlabcentral/answers/243868-mex-can-t-find-compiler-after-xcode-7-update-r2015b and notice the prefdir files mentioned in the comments on one of the Answers in that Question.

I recommend that you switch to using regular XCode 7 instead of using XCode beta.
After you install XCode, start up XCode and agree to the license agreement. Then run the above sudo command again. Then apply the patch described here . When that is all done, go in to MATLAB and use
mex -setup

Dear Sir, I uninstalled xcode beta and installed xcode7.Then run the sudo command. After this I simulated the simulink file, to my surprise it is working and running perfectly.Thanks a lot sir. Thank you very much. End to a long standing problem with matlab.
