I have a vector like something in attach file f0 and L was defined as two symbolic parameters. I want these parameters be like vector coefficient for [1/6;2/3;1/6] Thanks in advance

syms f0 L
r=f0*L*[1/6;2/3;1/6];
r =
(L*f0)/6
(2*L*f0)/3
(L*f0)/6
and
var=symvar(r)
var =
[ L, f0]

Not sure if it is the best way but you can try something like this :
syms f0 L
num=[1/6;2/3;1/6];
r=f0*L*num;
symbolicVariables=symvar(r)
symbolicVariables =
[ L, f0]
numericPart=zeros(length(r),1);
for i=1:length(r)
numericPart(i)=coeffs(r(i));
end
numericPart =
0.1667
0.6667
0.1667
