- Use the "which" command in MATLAB to check if the "pck" function is available and to determine its source location:
- If 'pck' is user-defined function and is not on the path, you need to add the directory to MATLAB’s search path.
- If it belongs to a specific toolbox, ensure that the corresponding toolbox is installed and that you have an active license for it.
- Additionally, verify the implementation of the pck function to ensure that the inputs are correctly formatted.
