I'm trying to use Matlab function. When I finish my simulation and click 'run' there is an error "Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler." I have no idea where is the 'mex-setup'. Could you fix that to me. Thanks in advance! Sorry with some mistakes in grammar. I'm not a native

At the command line give the command
mex -v -setup
That will give you information about where it looked for compilers and what compilers it found on your system. You will likely find that you do not have one of the supported compilers installed.
You can look at https://www.mathworks.com/support/sysreq/previous_releases.html to see which compilers are supported for MATLAB and for Stateflow for your MATLAB release.

I am using Windows 7 Ultimate. Does that mean I can't use the compiler cause my Windows version is not on the supported list.

Which MATLAB release are you using?
You should be able to use MATLAB provided that your release indicates it is available for Windows 7, and provided that you have SP1 or later

I am using MATLAB R2013a. Can I download a compiler somewhere?

Sorry for late reply. After downloading and installing the software, There is one more error occurred "Making simulation target "DTC_sfun", . . . 'DTC_sfun.bat' is not recognized as an internal or external command, operable program or batch file. "

I was clicking the 'Run' button and the error appeared. I have changed from a continuous solver to a discrete solver but there is the same error

It is not possible to just switch to discrete solver: you also need to discretize the model.
I am having some difficulties getting the powergui library block to interface properly -- but that is a number of steps further than you are getting.
There should be a number of lines of output before the message about DTC_sfun: please post those.
Also, please remind me which MATLAB version you are using.
