My current task is to convert a MATLAB program to C++, which contains image processing functions like imread, edge, strel, etc. Since it took a long time to finish the MATLAB program, so we want to take a shortcut instead of translating it in C++. I've tried MATLAB Coder, but it can't convert those MATLAB functions. So I tried another tool: MATLAB Compiler. Unfortunately, some errors block me going further. I posted a question here:

http://stackoverflow.com/questions/17120635/calling-matlab-from-c-errors-unresolved-external-symbol/17129313?noredirect=1#17129313

However, the problem hasn't been resolved yet. I'm appreciated it if you can answer my question in stackoverflow or here, but I'm more eager to know whether it is an efficient way to convert my MATLAB program to C++ by using MATLAB Compiler like what I've done? Are there any better ways to finish my task? Please give me any guide or advice to help.

It looks like you may not have configured your project correctly. Please try using the mbuild command as described in href = ">http://www.mathworks.com/help/compiler/c-shared-library-target.html#f2-1000836">this example</a first to see if you are able to compile your driver application.

Hi Yudong,

We currently do not support code generation for the image processing functions such as imread, edge, strel, etc and you are right about this. Functions http://www.mathworks.com/help/simulink/ug/functions-supported-for-code-generation--alphabetical-list.html are supported for code generation. You need the MATLAB Coder product. To support your workflow, I would suggest using the supported functions, generate code and qualify performance.

MATLAB Compiler might not be the right product for converting into C++ code. Its just a thin wrapper around the MEX files for easy deployment.

To determine if a function supports C/C++ code generation (and what limitations that function has if any when used in code generation) look at the documentation page. If it has a section titled "Extended Capabilities" see if that section has an item titled "C/C++ Code Generation". If it doesn't have an Extended Capabilities section or if that section doesn't have a C/C++ Code Generation item it is not supported for code generation.

The sde documentation page does not have an Extended Capabilities section so it is not supported in code generation. Compare that with the documentation page for the sum function which does support C/C++ code generation with a few caveats.

More generally you can filter the function list by product and by the different items under Extended Capabilities to see the list of functions supported for code generation.
