STL and Simulink Coder

How can I use STL with Simulink Coder? In particular I need to access a deque.

[Kaustubha Govind]

Do you mean that you want to access a deque in a Simulink block? Or do you want to pass in elements from a deque to code generated using Simulink Coder?

Hi James,

If you're trying to incorporate custom C++ code, including STL containers like std::deque, into your Simulink models, you can use S-Functions in your Simulink model. S-Functions allow you to integrate custom C/C++ code into Simulink. You can write an S-Function in C++ and use STL containers inside it.

• Create a C++ source file where you include the necessary STL headers and define functions to interact with std::deque.
• Write an S-Function wrapper in C/C++ that calls the C++ functions you've defined.
• Use the 'mex' command to compile the S-Function.
• Add the compiled S-Function to your Simulink model.
• Set up the inputs and outputs of the S-Function to match your C++ functions.

For more detailed information, pleaese refer to this documentation:

Hope it helps!
