The paper is freely available on arXiv

• MATLAB (tested with version R2023b running on Macbook Pro with M1 processor with 8 cores and 16GB of RAM running macOS Sonoma)
• Casadi (tested with casadi-3.6.4-osx_arm64-matlab2018b )

Only for performance comparison:

• Yalmip (tested with Version 22-June-2023)
• Mosek (tested with Version 10.3)
• Gurobi (tested with Version 10.0.3)

1. Download and install MATLAB from the official website.

2. Install Casadi by following the instructions from the official Casadi documentation.

3. (optionnal) If you want to run the comparisons

• Install Yalmip

• Download MOSEK, (request a license), and add it to your matlab path

      addpath('C:/Users/Documents/mosek/10.3/toolbox/r2022b/mosekopt.mexmaca64'); % Adjust this path to your MOSEK installation
      savepath; % Save the updated path for future MATLAB sessions
  

• Downlaod Gurobi, (request a license), and add it to your matlab path

      addpath('C:/Users/gurobi/macos_universal2/'); % Adjust this path to your Gurobi installation
      savepath; % Save the updated path for future MATLAB sessions
  

4. Clone this repository or download the code as a ZIP archive and extract it to a folder of your choice.

5. Add the code folder to your MATLAB path by running the following command in the MATLAB Command Window:

    addpath('/path/to/your/code/folder');
   

Run the main script (i.e., main.m) to execute the algorithms and models discussed in the paper.
