The partfrac() function can directly show you the answers for the values of A, B, C, D. But it doesn't show you the steps to compute those values.

Are you looking for the functions from the Symbolic Math Toolbox that can be used to solve the algebraic problems for calculating A, B, C, D separately?

Ran in:
I would use the partfrac function —
syms s
H = 8/((s^2+4)*(s+1)*(s+4))
H = 
Hpf = partfrac(H)
Hpf = 
You will likely need to interrpret the coefficients to get them in the forrm you want.
