Hi,
I am trying to generate a random integer between 0 and 15.
I have written the following code:
b=0;
B=15;
B = b + (B-b) * rand
Is it right?
Also, will the random integer generated from the above code have equal probability? Is not, how should the code be modified?

B=randi([0,15])

When you read the randi documentation, its description states on the very first line "Uniformly distributed pseudorandom integers". This means the integers have equal probability. It also means that you should learn to read the documentation, because it tells you how MATLAB works.

This is not a hard proof, but a strong hint already:
b = 0;
B = 15;
R = b + (B-b) * rand(1, 1e6);
histc(R, unique(R))
