Why am I getting error "Too many input arguments"

This is embarrassing... I can't figure out why it's saying "Too many input arguments."

Here's the definition. It seems to me that predict(...) takes 10 arguments:

classdef TrajectoryPredictor
% TrajectoryPredictor predicts a trajectory.
% Its predict() method returns data.  Other methods are private.
    properties
        model
        simParams
    end
    methods
function tp = TrajectoryPredictor(vehicleModel, simParams)
    tp.model = vehicleModel;
    tp.simParams = simParams;
end
 
function [trajectory_output, state_vector] = predict(...
                measure_vector, measure_time, ...
                previous_measure, previous_time, ...
                previous_state_vector, waypoints, ref_traj, ...
                lat0, lon0, alt0)
            etc

Here's the instance creation and the call to predict(), with line numbers added:

122        predictor = TrajectoryPredictor(model, simParams);
123        [predicted_traj, state_vector] = predictor.predict(...
124                loc_now,  t_now, ...
125                loc_prev, t_prev, ...
126                state_vector, waypoints, ref_traj, ...
127                lat0, lng0, alt0);

It sure looks to me like there are 10 arguments being passed. But I get:

Error using TrajectoryPredictor/predict
Too many input arguments.

Error in test_prediction>do_test_prediction (line 123)
        [predicted_traj, state_vector] = predictor.predict(...
            

(It really should say how many it sees and the number(s) it expects...)

[Randy Strauss]

I think I have to pass the instance into the method, sigh...

[Randy Strauss]

Either predictor has to be passed in,

or if it's called predictor.predict(...), it should omitted.

but it must be declared as the first parameter of the function in the definition...

(I prefered APL...)
