I am trying to create a function which gives me the result of running frequency of 1's in a single generated vector of size N=100.For example if N=4, and the vector b=[0 1 0 1],then the running frequency of 1's [0 0.5 0.3333 0.5] because the frequency of 1's until the first bit is 0. How can i write this function ?

b = your row vector of 1's and 0's
result = cumsum(b) ./ (1:numel(b));
