Hi Chandni,
You can use a MATLAB Function block in simulink to load the trained object detector .
To work with MATLAB Function block you can refer :
Inside the function you can have your custom code and make predictions like this
% Assuming trainedDetector.mat is the saved object detector
trainedDetector = load('trainedDetector.mat', 'trainedDetector')
I = imread('highway.png');
[bboxes, scores, labels] = detect(trainedDetector,I,Threshold=0.05);
detectedImg = insertObjectAnnotation(I,"Rectangle",bboxes,labels);
To read more about loading different types of variables, you can refer
