I am trying to create an array to compute the cumulative frequency of array Z, which are less than or equal to the time in minutes specified by the minutes array, V.
X1= sqrt(rand(1,1000));
X2= normrnd(20,5, 1,1000);
w= rand(1,1000);
X3 = (-log(1- w));
sz = [1 1000];
X4 = unifrnd(4,15, sz);
Z=X1+X2+X3+X4; %(note: Z is an array with 1000 values in one row)
V = linspace(1, 1000, 1000); %array V

This is inelegant, but it works:
cumFreq = zeros(size(V));
for i=1:numel(V)
cumFreq(i) = sum(Z<V(i));
