random number between 0 and 1

I want to create random vector between 0 and 1 for 412 elements, by using

logical(randi([0 1],[412,1]));

It's work. But now, I want to have the number of '0' is 100, the number of '1' is 312. How I can do?

>> V = [zeros(1,100),ones(1,312)];
>> V = V(randperm(numel(V)));

Checking:

>> nnz(V==0)
ans =  100
>> nnz(V==1)
ans =  312
>> V(:)
ans =
   1
   0
   1
   1
   1
   1
   1
... lots of rows here
   1
   1
   1
   1
   1
   0
   1
   0
   1
   1
   1

Hi

Instead of generating the array using randi function, you can create a zeroes array and pick 312 random indices and make them as one. Easy way to get what you want. Hope this helps.

x = zeros(412,1);
ind = randperm(412,312); %generates 312 unique numbers in the range 1 to 412
x(ind)=1;
