how to create new cumulative frequency array from two existing arrays

I would like to make an array from logic between two other arrays

So for code below when i want to make an array using a while loop for when logic Y <= v is fulfilled then new array being created will give me cumulative frequency.

for example:

Y= [ 5 5 3 4 5]

v = [ 4 3 3 4 6]

for Y <= X new array should be:

CumFreq = [ 0 0 1 2 3]

so frequency keeps compounding.

below are the two arrays i am trying to perform while loop on with Y<=v

mu = 50
sigma = 10
Y = normrnd(mu, sigma, 1,1000);
v = linspace(1,1000, 1000);

Hi BW,

mu = 50
sigma = 10
Y = normrnd(mu, sigma, 1,1000);
v = linspace(1,1000, 1000);
a = cumsum(Y<=v)
