Hi,
I am trying to caculate the total length of a symbolic expression.
Eg.

df=x^2+2*a*b
I want to cacluale the length of 'df', in my case the answer should be nine (including operator).
I am using MATLAB 2015a.
Any help please.

S = char(df) ; % convert sym to string
idx = strfind(s,' ') ; % get empty spaces
S(idx) = [] ; % remove the mepty spaces
iwant = length(S)
