   @edponce, `mexfcn` only receives input arguments from MATLAB. End users will interact with the MATLAB APIs, which will make use of `mexfcn`. `mexfcn` will dispatch to individual C++ functions that implement the necessary function specific behavior. 
   
   Depending on the needs of a particular C++ function, developers can pass options in the way that they deem appropriate, in order to get that information to the C++ layer. `mexfcn` accepts a variable number of input arguments, of any type, from MATLAB. So a developer could pass an options struct to `mexfcn` in order to propagate any options to the C++ layer. The translation from the options struct to C++ data structures would need to be taken care of by the specific C++ functions.
