How can I solve the compiler issue in matlab?

I am using matlab R2013a 64-bit version in windows 8.1. When i tried to simulate .m file,i got an error.The error is "Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler".How can i solve this?

You read http://www.mathworks.com/support/compilers/R2013a/index.html?sec=win64 and install SDK7.1 and NET 4.0, or you install Microsoft Visual C++ 2012 Professional, or you install Microsoft Visual C++ 2010 Professional SP1, or you install Microsoft Visual C++ 2008 Professional SP1 and Windows SDK 6.1. And then after you install one of those you run

mex -setup

Previously the error was unable to locate c compiler. I installed wnindows SDK 7.1 as per your instruction. But now another 3 errors are showing while running .m file. The errors are

1).Make-Making simulation target "nnwithbb_4_sfun", ... 'nnwithbb_4_sfun.bat' is not recognized as an internal or external command, operable program or batch file.

2).Parse -Parsing successful for machine: "nnwithbb_4"(#21)

3).Coder-Code Directory : "G:\Materials\MAIN PROJECT\nirupama\slprj\_sfprj\nnwithbb_4\_self\sfun\src"

Machine (#21): "nnwithbb_4" Target : "sfun"

Chart "PV module" (#23):

. "c2_nnwithbb_4.h"

     "c2_nnwithbb_4.c"

     "nnwithbb_4_sfun.h"

     "nnwithbb_4_sfun.c"

     "nnwithbb_4_sfun_debug_macros.h"

Interface and Support files:

     "nnwithbb_4_sfun_registry.c"

Code generation successful for machine: "nnwithbb_4" The above 3 are the errors .What should i do?
