Have you tried anything? Yes Matlab can do transfer functions, there are many approaches that you can take. – Matt Mar 31 '17 at 18:06

Do you have access to the Control Systems Toolbox? It'll make computing this very easy. – rayryeng Mar 31 '17 at 18:17

@rayryeng Yes I do can access, Could you explain more? – Kia Rash Mar 31 '17 at 18:50

The Symbolic Math Toolbox can be used here:
syms alpha theta delta s
% we have to solve the system
sol= solve([(88.5*s+3.13)*alpha+(-88.5*s+2.06)*theta==-4.63*delta,...
-11.27*alpha+(4.75*s^2+0.321*s)*theta==-34.25*delta] ,[theta delta])
tfuncsym= sol.theta/sol.delta % the transfer function (sym object)
[n,d]= numden(tfuncsym);
% the transfer function (tf object)
tf_object= tf(fliplr(double(coeffs(n))),fliplr(double(coeffs(d))))
% the transfer function (zpk object)
% this is exactly what we need
zpk_object= zpk(tf_object)
