MATLAB: Need syntax to store and preallocate the output from a for loop and use them for serial multiplication

store preallocate for loop outputs

Please how can i implement this for loop to get the serial multiplication
f  = 25 ;
m = 0:10:80;
Zcb = 104.5; 
l = 3.75e-3 ;
Zo = (1 + (0.055*(1-1i))/sqrt(f)); 
n = 800 ; 
x = 1; 
P = 800;
Z1 = 1+((m)*sin(2*pi*n*x/P));
ZB = abs(Zcb*Zo*Z1);
u = ((494)+(36/f))*1.0e-9;
Vpk = 100/u ; 
Attk = (1.80*sqrt(f)+ 0.005*(f)+ 0.25/sqrt(f));
Qk = ((Attk)*(0.01))/(8.68588963807); 
Bk = (2*pi*f*1.0e6)/(Vpk); 
Yk =(Qk + 1i*Bk);
H = (1.0000 + 0.0000i);
N = (0.0000 + 0.0029i); 
Ds = (2*ZB.*Zo*H) + ((ZB.^2+Zo^2)*N);
SB11 = ((ZB.^2-Zo^2)*N)/Ds;   
SB12 =  (2*ZB.*Zo)/Ds;        
SB21 =  (2*ZB.*Zo)/Ds;         
SB22 = ((ZB.^2-Zo^2)*N)/Ds;   
% Program to convert S matrix to T  matrix 
TB11 = ((SB12*SB21)-(SB11*SB22))/SB21; 
TB12 = (SB11/SB21);
TB21 = -(SB22/SB21);
TB22 = (1/SB21);
TB = [TB11 TB12;TB21 TB22];
% program to get the sequential product of TB from the for loop above
T = TB1*TB2*TB3*TB4*TB5*TB6*TB7*TB8*TB9*TB10;

Zo = 100;
H = (1.0000 + 0.0000i);
N = (0.0000 + 0.0029i); 
Ds = (2.1132e+004 +6.1764e+001i);
ZB = reshape(1:2:20,1,1,[]);
Ds = 2*ZB.*Zo*H + (ZB.^2+Zo^2)*N;
SB11 = (ZB.^2-Zo^2)*N./Ds;   
SB12 =  (2*ZB.*Zo)./Ds;        
TB11 = (SB12.^2-SB11.^2)./SB12; 
TB12 = SB11./SB12;
TB22 = 1./SB12;
out = prod([TB11 TB12;-TB12 TB22],3);
