MATLAB: Problem with mex

mexmex compiler

Hello,
I am using the R2010b version (x64). When I try to mex a C file, MATLAB shows the following:
LINK : warning LNK4044: unrecognized option '/lkernel32'; ignored 
LINK : error LNK2001: unresolved external symbol mexFunction 
C:\Users\CHAITA~1\AppData\Local\Temp\mex__573OQ\templib.x : fatal error LNK1120: 1 unresolved externals 
    B:\MATLAB~2\BIN\MEX.PL: Error: Link of 'Hk.mexw64' failed. 
??? Error using ==> mex at 208
Unable to complete successfully.
I have already set the installed compiler "Microsoft Visual C++ 2010 Express in C:\Program Files (x86)\Microsoft Visual Studio 10.0"
Please help!
Thanks…
PS. My Control panel shows that the following are present in my computer as well.
Microsoft Visual C++ Compilers 2010 Standard - enu - x64    ;    
Microsoft Visual C++ 2010 x64 Redistributable - 10.0.30319    ;     
Microsoft Visual Studio 2010 Express Prerequisite x64 - ENU    ;    
4. Microsoft Windows SDK for Windows 7 (7.1)

Hi,
the linker misses "mexFunction", i.e., the entry point. Did you spell "mexFunction" and it's arguments correctly? Take a look at the examples given in the doc and try to compile them (and compare your mexFunction entry with the one given in those).
