odd order calculation of filter

Dear all,

I am trying to find a way calculate my componet values from first order section of my Transfer function. How can I manipulate the code in Matlab to calculate the first order section. I put the code below and the results with error. This is 3rd order. Any response is highly appreciated.

code:
pp1=p{1}(1)/p{1}(3);pp2=p{1}(2)/p{1}(3);pp3=p{1}(3)/p{1}(3);
up=gain_c/p{1}(3);fsf=sqrt(p{1}(3));norm=(p{1}(2)/(p{1}(3))); Q=1/(fsf*norm)
R1 = 10000 % the value set.
R4 = R1/10^(dc/20)
R3 = (R1*R4/(R1+R4))
C5 =pp2/(2*R1); C2 = (pp1)/(R1*R3*C5);
C5=1/Bw*C5
C2=1/Bw*C2

% 4th order section
pp1b=(p{2}(1)/p{2}(3)); pp2b=(p{2}(2)/p{2}(3)) ;pp3b=(p{2}(3)/p{2}(3));
upb=gain_c/p{2}(3);fsfb=sqrt(p{2}(3));normb=(p{2}(2)/(p{2}(3)));
Qb=1/(fsfb*normb);
R1b = 10000 % the value set.
R4b = R1b/10^(dc/20)
R3b = (R1b*R4b/(R1b+R4b))
C5b = pp2b/(2*R1b);
C2b = (pp1b)/(R1b*R3b*C5b);
C5b=1/Bw*C5b
C2b=1/Bw*C2b
