Greetings,

I want to evaluate my Yolov3 model by plotting the Precision-Recall curve. I tried to follow the example provided in the "Object Detection Using Yolo v3 Deep Learning' (https://www.mathworks.com/help/vision/ug/object-detection-using-yolo-v3-deep-learning.html). However the error displayed as follows:

Error using plot

Not enough input arguments.

Error in testyolo (line 41)

plot(recall, precision);

May I know what is the problem with my code? My code is

celldetector = load('trainedyolov3Detector-2022-11-04-00-30-56.mat');
testData = combine(imdsTest, bldsTest);
detector = celldetector.yolov3Detector;
results = detect(detector,testData,'MiniBatchSize',8);
[ap,recall, precision] = evaluateDetectionPrecision(results, testData);
figure;
plot(recall, precision);
xlabel('Recall')
ylabel('Precision')
grid on
title(sprintf('Average precision = %.1f', ap))
