Test uniformity and sequential correllation for random numbers

How to test random numbers' uniformity and sequential correlation and how to give graphical analysis?

I produced my random numbers with the following code:

% first random number sequence
seed_1 = 10;
R1 = rand(seed_1);

% Second random number sequence
seed_2 = 53;
R2 = randi(seed_2, [10,10]);
