help in converting matrix

below is the codes using syms symbolic,may i know how to convert the matrix Z using the formular into h

syms s C R w h11 h12 h21 h22 y11 y12 y21 y22
%s domain
Z=[1 (s*C)+R ;0 1]  %matrix C series R
A=1
B=(s*C)
C=0
D=1
%formuar convert abcd to h
A= ((h11*h22)-(h12*h21))/h21
B=-h11/h21
C=-h22/h21
D=-1/h21
%convert z matrix using formular convertion

What is formular convertion?

[grace lim]

A=((h11*new)-.... B=-h11/h21 ,All listed there

[grace lim]

How do I do the conversion

Your not making any sense. We have no idea what you are talking about. You can solve for h-coefficients in terms of A, B, C, and D.

syms h11 h12 h21 h22 A B C D
eqn1=A== ((h11*h22)-(h12*h21))/h21;
eqn2=B==-h11/h21;
eqn3=C==-h22/h21;
eqn4=D==-1/h21;
h=solve([eqn1;eqn2;eqn3;eqn4],[h11 h12 h21 h22]);
