this is part for my project and it would be helpful if someone can help me in this
U = [(G*L*R_w - C_p^2*G*G_cp^2*s - C_p^2*G_cp^2*L*s^2 + C_p^2*G*G_cp^2*L*s^2 + C_p*G*G_cp*L*s + 2*C_p*G*G_cp*L*R_w*s - C*C_p^2*G*G_cp^2*L*s^3 + C_p^2*G*G_cp^2*L*R_w*s^2)/(G*L*(C_p*G_cp*s + 1)^2)]*I
This is in laplace domain and
G,L,C,R_w,C_p,G_cp are parameters
i need this in code
thanks in advance

Laplace transform (LT) formulation is already an anaytical form solution and if you would like to get a new fit (rational polynomial with the same orders for a numerator and denominator), that would be based the same formulation (rational polynomial) with the coefficients (known parameters): G,L,C,R_w,C_p,G_cp
You can practice this exercise using >> cftool() - curve fitting toolbox after oftaining some data from your LT formulation for some range of s = ... values.
Good luck
