Symbolic variable array problem

Hi, I am trying to create an array in symbolic variable. However I am not successful in this task, something is going wrong. I will welcome any help. My code

syms shafun
syms xp
nel=3;

for i=1:1:nel
    if i==1
        shafun(i,:)=([(xp-(le*i))/-le,(xp)/le]);
    else
    shafun(i,:)=([(xp-(le*i))/-le,(xp-(i-1))/le]);
    end
end

The result is shafun of size 3x1, but I am expecting it to be 3x2 as I am specifying two columns. Why only first column is computed and not second one for all rows? Any help? Thanks in advance.

You don't need to specify shafun as a symbolic variable, just push it out and you'll have shafun as a matrix of 3x2.
