Finding Corresponding values for graph/matrix.

I want to find the value of zxt when x=3 for different speeds(v), I've using x=3 and using a second loop but the numbers don't match up!
if true % code
ib=ones(101,1);
ia=[1:1:101];
i=ib*ia;
l=6;
xa=[0:1:100];
x2=reshape(xa,101,1);
x1=ones(1,101)*l/100;
x=x2*x1;
r=98000;
u=13875;
ei=1676500000;
e=0.0;
b=e/sqrt(1-e^2);
f1=15.16;
w1=2*pi*f1;
wb=e*w1/sqrt(1-e^2);
wi=2*pi^2*i.*i*sqrt(ei/u)/(2*l^2);
wi1=sqrt(wi.^2-wb^2);
for v=1:160;
t=x/(v*0.25);
w=pi*v*0.25/l;
a=w/w1;
zxta=2*r*l^3/(ei*pi^4);
zxti=sin(i.*x.*pi./l);
zxtii=i.^2.*(i.^2.*(i.^2-a^2)+4*a^2*b^2);
zxtb=zxti./zxtii;
part1=i.^2.*(i.^2-a^2).*sin(t.*i.*w);
part2=(-a*i.*(i.^2.*(i.^2-a^2)-2*b^2)./(i.^4-b^2).^0.5).*exp(-t.*wb).*sin(t.*wi1);
part3=-2*a*b*i.*(cos(t.*i.*w)-exp(-t.*wb).*cos(t.*wi1));
zxtc=part1+part2+part3;
zxtd=zxtb.*zxtc;
zxte=sum(zxtd,2);
zxt=zxta*zxte;
temp_fdaf=max(zxt);
fdaf(v)=temp_fdaf;
end
V=[0.25:0.25:40];
plot(V,fdaf)
if true
% code
end
Thanks!

Don't double space. Just highlight the code and click the {}Code button. Don't click the code button first, or if code is not highlighted. Please read this: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup
