### FMI Toolbox in MATLAB Installation and Usage #### Compatibility and Requirements To work with Functional Mock-up Interface (FMI) within MATLAB or Simulink®, one requires the Easy Co-simulation (FMI) add-on for these environments. This tool facilitates exporting models as FMU files which then can be utilized across systems supporting Simulink®[^1]. For operations involving parameter adjustments, m-files serve compatibly alongside this module during exports. #### Installation Process For installing the FMI toolbox specifically designed for MATLAB: - Ensure possession of a valid Simulink® license since no additional modules beyond this are necessary for leveraging FMI functionalities. After acquiring the appropriate version from MathWorks or an authorized distributor, ```matlab % Add-On Manager approach openAddOnManager; ``` Search for "FMI" under the available categories and proceed through guided prompts to complete setup. Alternatively, direct downloads may also come packaged with installer scripts executable via command line: ```bash !install_fmi_toolbox.sh % On Unix/Linux/MacOS !install_fmi_toolbox.bat % On Windows ``` #### Basic Usage Instructions Once installed successfully, initiating co-simulations becomes straightforward using built-in functions provided by the package. Exporting Models: Creating FMUs involves specifying target settings followed by invoking relevant commands. ```matlab set_param('model_name', 'FMIAbsolutePath', pwd); export('model_name'); ``` Loading External FMUs into MATLAB Workspace: Import capabilities although mentioned as forthcoming at some point might not yet fully roll out; however, existing support allows handling exported entities effectively. ```matlab fmuObject = fmi.import('path_to_fmu_file.fmu'); setup(fmuObject); % Prepare imported model for simulation simOut = sim(fmuObject); % Run simulations directly on loaded object ``` --related questions-- 1. What specific versions of MATLAB/Simulink® does the current release of FMI Toolbox officially support? 2. How do custom parameters defined inside M-files integrate when generating FMUs? 3. Are there limitations regarding types of blocks that can participate in forming an FMU exportable unit? 4. Can users expect full bidirectional interoperability between different simulation platforms once adopting standardized FMU formats generated here?
