Syntax

params = tunedParameters(tuner)

Description

params = tunedParameters(tuner) returns the tuned parameters from the tuner.

Tip

  • When tuning a trackingFilterTuner object by using its tune object function, the trackingFilterTuner object saves the tuned parameters at each solver step. Use the tunedParameters function to retrieve the tuned parameters.

  • If you changed any of these properties of the trackingFilterTuner object, run the tune object function before using the tunedParameters function.

Open Live Script

Load the tuning data containing the truth and detection data.

load("filterTuningData.mat","truth","detlog");

Create a trackingFilterTuner object. By default, the FilterInitializationFcn property of the tuner initializes a trackingEKF object.

tuner = trackingFilterTuner;
tune(tuner,detlog,truth);

Obtain the tuned parameters.

tunedParams = tunedParameters(tuner)
tunedParams = struct with fields:
       ProcessNoise: [3×3 double]
    StateCovariance: [6×6 double]

Input Arguments

collapse all

Tracking filter tuner, specified as a trackingFilterTuner object.

Output Arguments

collapse all

Tuned parameters, returned as a structure. The exact fields and values of the structure vary based on the specific filter.
