Randomizing samples without losing track on labels

I have 5 different images data and I want to shuffle/randomize each time when displayed. I want to keep track on which image I am showing. How I can do it in matlab? For example I have images of cat, dog, cows, lions and tigers. I want to show them to users for 5 trials. How I can keep a track on their labels. Is there any data structure like keys and values in python which can be implemented in Matlab?

Hi Vivek,
There are many examples provided in the link. I'll attach one of them here, but you could always go back to explore more.
wheels = [1 2 3];
names = ["Monocycle" "Bicycle" "Tricycle"];
d = dictionary(names,wheels)
d("Tricycle")
d("Bicycle") = 2.5
d("Car") = 4
names2 = ["Truck" "Motorcycle" "Sixteen-Wheeler"];
wheels2 = [4 2 16];
d(names2) = wheels2
d("Truck") = [] % Remove entries by assigning an empty array to an existing key.
