How to create array from saved iterations of a loop

I am wondering how I would create an array of numbers from a loop in matlab. After every iteration a number is saved and I want to be able to put all these outputs in one array. My outputs look like

x = 2
x = 3
x = 4 

and so on.....

I want it so at the end of the loop the answer says

x = [2,3,4]

Thank you in advance

For anyone wondering, initialise

x = [];

and then to call it outside the loop

x = [x,y]

Just store them column by column

for jj = 1:1:5
	x(jj) = jj
end

this doesn't work for me because it just keeps iterating over heaps changing variables

I do not know how your code is working but if you are getting values saved (as you said in question) then you should be able to save them as arrays
