Getting the coefficients of a function in Matlab syms

How would I be able to get the Coefficients of the f function down below and get the Expected Output?

Code:

syms a b
f = expand((a+b)^2)

Expected Output:

1 2 1

[DGM]

Try

syms a b
f = expand((a+b)^2)

f = 

c = coeffs(f) % if you want a symbolic result

c = 

c = double(c) % if you want a numeric result

c = 1×3

1 2 1
