create one to one function between a rows of 2 vectors

I'm fairly new to Matlab and I'm looking to create a function that assigns the first n numbers in their binary form to a random number between 0 and 1. This is what I've got so far but it isnt really working.

n=3
d2b = de2bi(0:2^n-1)
randnos = rand(2^n,1)
f=@(x) randnos(find(d2b(x,:)==x));
f(d2b(1,:))

Any help would be greatly appreciated!

Take the input binary number and convert it to decimal, add 1, and use that to index the table of random numbers.
