    This occurs because "rotateframe" is a method of the "quaternion" class. Once the class definition for the "quaternion" class is loaded into memory, e.g. when a "quaternion" object is instantiated into the workspace, then the issue should not occur. To confirm, execute the following commands:
     
     
    >> quaternion
>> help rotateframe
>> which -all rotateframe
    Alternatively, to learn about how to use the "rotateframe" function without the need to instantiate an object of the "quaternion" class, you can either execute the "doc" command to search the  documentation for "rotateframe",
     
     
    >> doc rotateframe
    or you can execute the following command to directly return the Help information for "rotateframe":
     
     
    >> help quaternion.rotateframe
