Hi guys

Any idea for adding how to to add function measuring frame per seconds when deploying the following code to jetson nano

function yolo2detectobject()
%#codegen
%Copyright 2019 - 2019 The MathWorks, Inc.
%Load the pre-trained    detection network
persistent yolov2Obj;
if isempty(yolov2Obj)
        yolov2Obj = coder.loadDeepLearningNetwork('detectorYolo2.mat');
end
hwobj = jetson;
w = camera(hwobj,"vi-output, imx219 6-0010",[1280 720]);
d = imageDisplay(hwobj);
for k = 1:1800
    % Capture the image from the webcam on hardware.
   I = snapshot(w);
    I=imresize(I,[640 480]);
    
    % Run the detector on the input test image
    [bboxes, scores, ~] = detect(yolov2Obj, I,'Threshold',0.5);
    
    % Insert bounding box to test image
    I = insertObjectAnnotation(I, 'rectangle', bboxes, scores);
    
    % Display output on the target monitor
    image(d, I);
    
end
end
