Given a positive integer find whether it is a balanced number. For a balanced number the sum of first half of digits is equal to the second half.

Examples:

 Input  n = 13722 
 Output tf is true

because 1 + 3 = 2 + 2.

 Input  n = 23567414 
 Output tf = true

All palindrome numbers are balanced.

This is partly from Project Euler, Problem 217.

there is a problem with the test.
it does not accept the following code:
s1=[]
s2=[]
l=length(s)
if mod(l,2)~= 0
for i = 1:ceil(length(s)/2)-1
s1 = [s1,str2double(s(i))]
end
for i = ceil(length(s)/2)+1:l
s2=[s2,str2double(s(i))]
end
else
for i = 1:ceil(length(s)/2)
s1 = [s1,str2double(s(i))]
end
for i = ceil(length(s)/2)+1:l
s2=[s2,str2double(s(i))]
end
end
