likelihood

Likelihood of measurement from tracking filter

Since R2021a

Syntax

measlikelihood = likelihood(filter,zmeas)

measlikelihood = likelihood(filter,zmeas,measparams)

Description

measlikelihood = likelihood(filter,zmeas) returns the likelihood of a measurement, zmeas, that was produced by the specified filter, filter.

measlikelihood = likelihood(filter,zmeas,measparams) specifies additional parameters that are used by the MeasurementFcn of the filter.

If filter is a trackingKF or trackingABF object, then you cannot use this syntax.

Input Arguments

filter — Filter for object tracking

trackingKF object | trackingEKF object | trackingUKF object

Filter for object tracking, specified as one of these objects:

• trackingKF — Linear Kalman filter

• trackingEKF — Extended Kalman filter

• trackingUKF — Unscented Kalman filter

• trackingABF — Alpha-beta filter

zmeas — Current measurement of tracked object

vector | matrix

Current measurement of a tracked object, specified a vector or matrix.

measparams — Parameters for measurement function

cell array

Parameters for measurement function, specified as a cell array. The parameters are passed to the measurement function that is defined in the MeasurementFcn of the input filter. If filter is a trackingKF or trackingABF object, then you cannot specify measparams.

Output Arguments

measlikelihood — Likelihood of measurement

scalar

Likelihood of measurement, returned as a scalar.
