MATLAB equivalent for Python code for argmax from array of user defined objects

Hi, I have an array as shown here. here Bandit is a class I created.

bandits = [Bandit(m1),Bandit(m2),Bandit(m3)];

Now, I want to do the following. Following is a python code which immediately gives me the maxarg of the value of mean from each of these objects.

 j = np.argmax([b.mean for b in bandits])

How can I do the same in MATLAB? Kindly help.
