As per my understanding, you are getting the following warning when trying to start the Parrot Mini-Drone:
Warning: Undefined function 'designfilt' for input arguments of type 'char'.
Please refer to the below pointers to resolve the issue:
- This warning occurs if one doesn't have the "Signal Processing Toolbox" installed, and that is why MATLAB is not recognizing the "designfilt" command.
- Installing the "Signal Processing Toolbox" should resolve the issue.
