Symbolic variable array problem

4 views (last 30 days)
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.
