How do I get each iteration of a for loop into a single row matrix?

Here I am getting each iteration correctly but I need pmf to be a row matrix with the answers from 0 to max(Data).
function [pmf] = CalcRelFreq(Data);
for range = 0:max(Data)
pmf = [1 ;sum(Data == range)/length(Data)]
end

What is size(Data)? Please provide a small example input and desired output. pmf looks like a column vector, so it is unclear how you want these stacked into a row vector.

I actually don't need it to be a row vector a column vector is good but still unsure how to do it
the input is userData which is a 20x1 matrix =
