implement for loop program

Please can anyone help me with this for loop program. I have this problem with making the outputs from the for loop do serial multiplication.
f = 25 ;
for 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];
end
% program to get the sequential product of TB from the for loop above
T = TB1*TB2*TB3*TB4*TB5*TB6*TB7*TB8*TB9*TB10;

I use Scilab, but probably Matlab is very similar.
If you have the 2x2 matrices TB1, TB2, TB3...TB10, you can define an hypermatrix TH (in this case a vector of matrices) as:

TH(1:2,1:2,1)=TB1;
TH(1:2,1:2,2)=TB2;
.
.
TH(1:2,1:2,10)=TB10;

then the product can be calculated as:

T=TB1;
for i=2:10,
T=T*TH,:,i);
end

The 2x2 matrix product of TB1 to TB10 is T.
