How would i store data into a vector

What i want to do is create a vector with only 1's that has a varying size depending on how i want it to be, since i know dynamically creating variables is not good i thought about creating a matrix of zeroes and storing the values i want in it, how would i do that? Also if there is another way of doing it please help.

numElements=10;

%Create 1x10 row vector filled with zeros
rowVector=zeros(1,numElements)
%Create 1x10 column vector filled with ones
colVector=ones(numElements,1)

colVector(5)=10 %Store the value 10 in the fifth element of colVector
rowVector(2)=22 %Store the value 22 in the second element of rowVector

Perfect, thanks! I didn't know you could use 'ones' likes 'zeroes'
