getting Not enough input arguments. error while trying to build a transfer function for a MISO system

hi, I am trying to anlyse a system of two inputs and one output and draw a bode plot. the equation is very simple:

G(s)=C*inv(sI-A)*B

while A is a 6*6 matrix C is 2*6 matrix and B is 6*2 matrix:

clc 
clear all
syms x1 x2 x3 x4 x5 x6 S G(S) g1 g2 g3 g4 S s
syms E1 E2 C1 C2 C L1 L2 L d1 d2 R
E1=25;
E2=12;
C1=33e-6;
C2=C1;
C=1500e-6;
R=5;
L1=340e-6;
L2=L1;
L=300e-6;
d1=0.293;
d2=0.473;
tspan = [0 0.15];
con=[0 0 0 0 0 0];
f = @(t,x) [(E1+x(4)*(d1-1)+x(5)*(d2-d1)+x(6)*(d2-1))/L1;(E2+x(5)*(d2-1-d1)+x(4)*d1+x(6)*(d2-1))/L2;(d1*x(4)+x(5)*(d2-d1)-x(6)*(1-d2))/L;(-d1*x(3)-d1*x(2)+(1-d1)*x(1))/C1;((1-d2+d1)*x(2)-(d2-d1)*x(1)-(d2-d1)*x(3))/C2;((1-d2)*(x(1)+x(2)+x(3))-x(6)/R)/C];
[t,xa] = ode45(f,tspan,con);
A=[0 ,0 ,0 ,-(1-d1)/L1, (d2-d1)/L1 ,(d2-1)/L1 ;
 0 ,0 ,0 ,(d1/L2) ,-(1+d1-d2)/L2 , -(1-d2)/L2 ;
 0 ,0 ,0 ,0 ,0 ,-(1-d2)/L ;
 (1-d1)/C1 , (-d1/C1) , (-d1/C1) ,0 ,0 ,0;
 (d1-d2)/C2 , (1+d1-d2)/C2 , (d1-d2)/C2 , 0, 0, 0;
 (1-d2)/C ,(1-d2)/C ,(1-d2)/C , 0, 0, (-1/(R*C))];
B=[(x4-x5)/L1 , (x5+x6)/L1 ; 
  (x4-x5)/L2 , (x5+x6)/L2 ; 
  (E1-E2)/L , (E2+x6)/L ;
  -(x1+x2+x3)/C1 , 0 ; 
  (x1+x2+x3)/C2 , -(x1+x2+x3)/C2;
  0 , -(x1+x2+x3)/C];
C=[1,0,0,0,0,0;0,0,0,0,0,1];
I=[1,0,0,0,0,0;0,1,0,0,0,0;0,0,1,0,0,0;0,0,0,1,0,0;0,0,0,0,1,0;0,0,0,0,0,1];
G=C*(inv(S*I-A))*B

the results give me a couple of problems. the first one is that I get an odd '\\\r\n' chars in the middle of the tranfer functions and while checking to see what that is I read that it's a bug that occurs when the expretion is too big. I tried to change it with change and replace (I took G(1,1) just for the testing):

newStr = strrep(G(1,1),'\\\r\n' ,'')

but I get an error that said:

Error using strrep
Conversion to double from sym is not possible.

and when I try to get a bode plot of G(1,1) I get this error:

Not enough input arguments.

I tried to delete the weird chars manually by setting a new variables but I still get the same error.
