mixing randomly existing values in a vector

hello I have a vector of 10 components - [1 1 1 1 1 1 0 0 0 0] I want to randomly (a uniform distribution is preferred) mixing the components of the vector, while making sure that in the end I will have the same amount of 1 and 0 as in the beginning.

a desired result for example: [1 0 1 0 1 0 1 0 1 1]

>> a=[1 1 1 1 1 1 0 0 0 0];
>> r = a(randperm(length(a)))

r =

       1     1     0     1     0     1     0     1     0     1
