Can you help me with creating .mat file with 85 images?

Sure, start a new question and say why you need that versus just having the images stored in normal files in a folder, or using an imageDatastore, after reading this:

How about subtracting them? We have no idea how you'd like to compare the test image to the images stored in the .mat file.

Walter Roberson i have seen that link 2 days back, but the problem is i cant understand whether i have to give the region that i am interested in every image in positive sample which is saved in .mat file.As i need to identify car in the image whether i have to draw the box around the car in every image in the positive sample before saving them in .mat file.
please give me clarification on that.
thanks

If you have the bounding box, you can call imcrop() to save that subimage to a file - you don't actually need to plot the box around the car in the overlay in order to crop it and save it.
