checkConfirmation

Check if track should be confirmed

Since R2020a

Syntax

tf = checkConfirmation(historyLogic)

Description

tf = checkConfirmation(historyLogic) returns a flag that is true when at least Mc out of Nc recent updates of the track history logic object historyLogic are true.

Examples

Check Confirmation of History-Based Logic

Create a history-based logic. Specify confirmation threshold values Mc and Nc as the vector [2 3]. Specify deletion threshold values Md and Nd as the vector [3 3].

historyLogic = trackHistoryLogic('ConfirmationThreshold',[2 3], ...
    'DeletionThreshold',[3 3])

historyLogic = 
  trackHistoryLogic with properties:

    ConfirmationThreshold: [2 3]
        DeletionThreshold: [3 3]
                  History: [0 0 0]

Initialize the logic, which records a hit as the first update to the logic. The confirmation flag is false because the number of hits is less than two (Mc).

init(historyLogic)
history = output(historyLogic);
confFlag = checkConfirmation(historyLogic);
disp(['History: [',num2str(history),']. Confirmation Flag: ',num2str(confFlag)]);

History: [1  0  0]. Confirmation Flag: 0

Update the logic with a hit. The confirmation flag is true because two hits (Mc) are counted in the most recent three updates (Nc).

hit(historyLogic)
history = output(historyLogic);
confFlag = checkConfirmation(historyLogic);
disp(['History: [',num2str(history),']. Confirmation Flag: ',num2str(confFlag)]);

History: [1  1  0]. Confirmation Flag: 1

Input Arguments
