How to generate random number in [0, 1] range

I am using rand(1) function which gives random number in between 0 and 1. But is there any function which will give random number between 0 and 1 & includes 0 and 1 as well, i.e in the interval [0,1]?

Not any of the Mathworks supplied ones.

Not unless philox4x32_10 or threefry4x64_20 can do it (not explicitly documented).

However, you could potentially use

randi([0 2^52]) / 2^52

which would differ from rand() in that rand() is 53 bits and this would be 52 bits.

I have not seen any information as to how randi() ensures fairness.

Note: randi([0 2^n]) is a range of ((2^n)+1) values, not a range of 2^n values.
