Will you please rectify the errors in the program?

I am not able to plot graphs between lateral straggle and threshold voltage and lateral straggle is varying between 2nm to 5 nm.

Arti run this code and you will see the graph:
Nde = 2.7*10^19;
Nsdp = 1*10^20;
lateralstraggle = 2*10^-9;
seff = log(Nde/Nsdp)*(-2*(lateralstraggle)^2);
Lg=70*10^-9;
Leff=Lg-(2*seff);
Deff=seff+Leff;
k=1;
T=20;
q=1.6*10^-19;
Vt=(k*T)/q;
ni=1;
Eg=1.17*1.6*10^-19;
nieff=(ni^2*exp(Eg/k*T))^1/2;
Nde=2.7*10^19;
Na=56;
Vbi=Vt*log(Nde*Na/(nieff)^2);
epsilon=32;
epsilonox=4;
tsi=20*10^-9;
tox=1.2*10^-9;
lambda=(epsilon*tsi*tox)/(2*epsilonox);
vgs=2;
vfb=1;
q=1.6*10^-19;
Na=56;
Nsdp= 1*10^20;
x=4.6*(1.6*10^-19);
lateralstraggle=7:70; % Here many values for lateralstraggle to see multiple values on graph
Nsdx=Nsdp*exp((-x^2)./(2*lateralstraggle.^2));
Lg=4;
Sd=4;
Nde=2.7*10^19;
Ei0=0.054*(1.6*10^-19);
Ei=Ei0*(1-(Nsdx/Nde).^1/3);
Eg=34;
eg=24;
Egeff=Eg-eg;
Ed= Egeff-Ei;
Ef=8;
Eg=3;
ni=8;
nieff=(ni^2*exp(Eg/k*T))^1/2;
Nsdx=Nsdp*exp((-x^2)./(2*lateralstraggle.^2))+Nsdp*exp((-(Lg-x)/2*lateralstraggle.^2))/(1+Sd*exp((Ef-Ed)/k*T));
PI=(vgs-vfb)-lambda^2*q*(Na-Nsdx)/epsilon;
Vds=1.3607e+003;
c2=((Vbi-PI)*(1-(exp(-Deff/lambda))/(exp(-seff/lambda))+Vds))/(exp(Deff/lambda))-(exp(seff/lambda))/(exp(-seff/lambda))*(exp(-Deff/lambda));
c1=(Vbi-c2*exp(seff/lambda)/exp(-seff/lambda))*exp(-Deff/lambda);
si=c1*exp(-x/lambda)+c2*exp(x/lambda)+PI;
Ni=2;
fi=Vbi*log(Na/Ni);
Na=3;
Vth=vfb+(2*fi)-(c1*exp(-x/lambda))-(c2*exp(x/lambda))+(lambda^2)*q*(Na-Nsdx)/epsilon;
plot(lateralstraggle,Vth)
ylabel('Vth, V')
xlabel('lateralstraggle,nm')
Is it what you are looking for?

Make sure you're plotting an array, not a single value, if that's what you want. See this : http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/

I know you did not ask a question but I sense confusion so, this should help: http://www.mathworks.com/matlabcentral/answers/8026-best-way-s-to-master-matlab

Difficult to do without your code.

If I had to guess, I'd say take a look at line 42 - it looks very odd.

An even odd number would certainly be a very odd odd number.

What program, or pgm as you call it? I don't see any program. Please look at exactly what you have posted so you know what I have to work with.

The attachment did not make it again. Is it the same as in your other question?

If this code is the same as in your other question, then how does this question differ from your other question ?

You do get a graph. I have run the program myself. It is a graph with a single point. Which is what you should expect as you have no vectors and no loops in your code.

ARTI, we just run your code. It's not worth our time to try to figure out what's going on. It looks like a dictionary exploded and the confetti rained down upon my computer. No comments or descriptive variable names. I don't know what all those variables are or what you intend to do. It just looks like an alphabet soup to me. So all I do is run it and see that a graph does indeed get created.
