Integrating external C/C++ code with MATLAB can be challenging, but it is possible to call C functions from MATLAB using the MATLAB Coder toolbox. Here are some steps to try:
- Install the MATLAB Coder toolbox if it is not already installed.
- Modify the C/C++ code to expose the desired functionality as a C function with C linkage.
- Compile the modified C/C++ code into a shared library or DLL using the MATLAB Coder toolbox. You will need to include the GSL library as part of the compilation process.
- In MATLAB, use the loadlibrary function to load the shared library or DLL containing the C function.
- Use the calllib function to call the C function from MATLAB, passing in any necessary arguments and retrieving any return values.
It sounds like you have already attempted step 4 using the coder.ceval function, which is similar to calllib but designed for use with the MATLAB Coder toolbox. However, if you are encountering issues with dependencies and linking, it may be helpful to try compiling the code into a shared library or DLL as described in step 3.
Keep in mind that modifying and compiling external code requires a solid understanding of both the original code and the MATLAB Coder toolbox. It may be helpful to consult with a MATLAB expert or reach out to the code authors for assistance.
