Errors related to Simulink containing Embedded Matlab Function

I am using Matlab R2011a version 7.12.My platform is windows 7 and 64 bit.When i try to run the simulink model containing embedded function,I get the following error.

"Making simulation target "New_sfun", ...

C:\Users\nitin\Documents\MATLAB\slprj\_sfprj\New\_self\sfun\src>call "mexopts.bat" 'nmake' is not recognized as an internal or external command, operable program or batch file. "

 I installed 
1.Microsoft Visual studio 2010 SERVICE PACK
2.Microsoft Visual Express c++ 2010 express
3.Microsoft Software Development kit 7.1
4 .NET Framework 4.0

Please kindly help me with this.I searched a lot in the internet,but couldn't solve my problem.

You need to run the "mex -setup" command and select your installed compiler.

[Nitin Reddy Ganna]

I tried the same earlier and selected Microsoft Visual Studio C++ 2010 Express as my compiler, but still couldn't solve my problem.

[Kaustubha Govind]

Did the message from "mex -setup" says that the options file was updated successfully? Could you try deleting the "slprj" directory in the folder and try again.

[Nitin Reddy Ganna]

After running "mex -setup" command here is what comes:

"Please verify your choices:

I have tried deleting the "slprj" directory,but still no use.

The same error appears.

[Kaustubha Govind]

Do you have C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\nmake.exe present on your machine?

[Nitin Reddy Ganna]

Yeah..

I tried to run the same simulink model in 32-bit operating system.It was running fine.

The compiler there was "lcc win-32".

[Kaustubha Govind]

Okay - try this in a Windows (system) command prompt:

> call "C:\Users\nitin\AppData\Roaming\MathWorks\MATLAB\R2011a\mexopts.bat"

> nmake /?

What do you see?

[Nitin Reddy Ganna]

"'nmake' is not recognized as an internal or external command,operable program or batch file."

[Kaustubha Govind]

Open up C:\Users\nitin\AppData\Roaming\MathWorks\MATLAB\R2011a\mexopts.bat in an editor and see if "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin" is being added to the system PATH variable correctly. Note that you might need to chase down values of variables such as VCINSTALLDIR that are created earlier in the same batch script.

[Nitin Reddy Ganna]

It's still not working.I re-installed matlab and this time when i run the mex -setup i get different error:

"

Error: Could not find the 64-bit compiler. This may indicate that the

"X64 Compilers and Tools" or the Microsoft Windows Software

[Kaustubha Govind]

See footnote#3 here: http://www.mathworks.com/support/compilers/R2011a/win64.html - by default Visual Studio only installs compilers for 32-bit targets. Since you are using 64-bit MATLAB, you need to make sure that you install the x64 Compilers and Tools package with Visual Studio.

[Nitin Reddy Ganna]

Here is the mexopts.bat file.I cross checked it with the batch file created where the model could be simulated.Both of them were same.Please notify the changes to be made if any.

[Kaustubha Govind]

You shouldn't need to change the mexopts.bat file - it looks like something is wrong with your compiler installation or System PATH variable. Did you install the x64 compilers as I suggested?

[Nitin Reddy Ganna]

Hmm..Ya i have installed them

[Kaustubha Govind]

Does "mex -setup" locate your compiler automatically now?

[Nitin Reddy Ganna]

Yeah..

Okay - it looks like this is going nowhere. I would recommend contacting Tech Support if you have a license that is on maintenance.
