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

[James Tursa]

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 =

Data=[    11

    10
    13];

pmf=histcounts(Data,0:max(Data)+1)'/length(Data),

pmf = 18×1
