Using shared pointers with MATLAB Coder

Hello guys,

My question is actually pretty straightforward. How do I use shared_ptr with generated C++ code from MATLAB? For example, I can pass a shared_ptr instead of a regular ptr to MATLAB-generated functions? If yes, how?

My first thinking is that I would have to change it manually in the function declaration, but I believe I could be so susceptible to errors this way.

Hi @Pedro Calorio,

For smart pointers, while MATLAB Coder doesn't generate shared or unique pointers, it can wrap dynamic memory allocation in a more modern interface that guards calls to "new" with a wrapper called coder::array. This should be safer than emxArrays. You can do this by setting DynamicMemoryAllocationInterface to 'C++' which should be the default when generating C++ code.
