How to auto generate wrapper for MatLab coder generated file?

I am looking for help in using the MatLab generated DLL into my application directly. I have created a simple function in MatLab:

function [RetVal] = CalculateSum(SingleDimArray)
  RetVal = sum(SingleDimArray);
end

Then I used a MatLab coder to generate a C/C++ DLL, which generates binary with following syntax:

double CalculateSum(const emxArray_real_T * SingleDimArray);

My application is having different requirement for using a DLL so I have created another DLL to wrap the DLL generated from MatLab coder like:

extern "C" __declspec(dllexport) void MyCalculateSum(VARIANT* Input, double* RetVal)
{
   //Fetch Input array
        SAFEARRAY *pInputArray = *(Input->pparray);
        long arraySize = pInputArray->rgsabound[0].cElements;
        double *pData = (double *) pInputArray->pvData;

          //Create Input Args - Wrapper for MatLab generated code
          emxArray_real_T *MLInputArray = emxCreateWrapper_real_T(pData, 1, MySize);

          //Call MatLab functions
          *RetVal = CalculateSum(MLInputArray);

          //Release the struct
          emxFree_real_T(&MLInputArray);   
  }

Currently I am doing this manually. Is there any way to generate this wrapper code through MatLab coder itself? If so then I can use the binary generated by MatLab coder directly in my application. I explored the possibility of including the “Custom C Code for Generated Files” but the content that I need to feed is static. I would like to know is there any way to generate the wrapper code for all the functions which is compiled from MatLab coder. I am trying to explore the “Code Replacement Library” option but didn’t get good example. Please throw some light on this area.

I do not think that there is a way to do this. You will probably have to do it manually.

See if the following link helps

http://www.mathworks.com/help/coder/ug/replace-code-generated-from-matlab-code.html

it has some information on code replacement.

It was really nice if there was an option to generate a code which an its entry point use regular types of C.

Namely regular pointers of C to arrays instead of the types defined by MATLAB.

To the leats you could add an auxiliray function which its input is a regular array of C and a vector of its dimensions and a scalar of the number of dimensions and its ouptut is the types of Coder.

At the moment coder yield a code which isn't fun to integrate to other projects.
