I am trying to use value of g0 from (a) to (b), can anyone please correct me...
d1=20;
n=10^-11.4;
ne=0.5;
m=2.7;
a=0.01:0.01:0.5;
T=1;
PsByN_0dB=5;
PsByN_0=10.^(PsByN_0dB/10);
UmaxdB = 5;
UmaxN_0=10.^(UmaxdB/10);
fun1 = @(u,a) (-1./u).*log(((d1^m)./(a.*ne.*PsByN_0.*T.*u+d1^m).*a)./(1-a));
fun2 = @(u) (1./u).*log(((-exp(u.*UmaxN_0).*(exp(-PsByN_0.*u)))./(u.*UmaxN_0+PsByN_0.*u)).*(PsByN_0.*u)-(PsByN_0.*u.*(exp(-PsByN_0.*u))).*(expint(u.*UmaxN_0+PsByN_0.*u))+(exp(-PsByN_0.*u))+((PsByN_0.*u).*(exp(-PsByN_0.*u))).*(expint(PsByN_0.*u))+(exp(u.*UmaxN_0))./((UmaxN_0/PsByN_0)+1));
fun = @(u,a) (fun1(u,a) - fun2(u));
options = optimset('Display','none');
g0 = arrayfun(@(a)fsolve(@(u)fun(u,a),[0.01],options),a); %a
d0 = @(g0,a) (-1./g0).*log(((d1^m)./(a.*ne.*PsByN_0.*T.*g0+d1^m).*a)./(1-a)); %b

You mean
d0 = fun1(g0,a)
?

You vary "a" and you vary "PsByN_0dB".
So you get a matrix of dimension
numel(a) x numel(PsByN_0dB)
as result for Pout.
Thus you can plot Pout with respect to the variation of "a" with "PsByN_0dB" fixed
plot(a_array,Pout(:,10).')
or you can plot Pout with respect to the variation of "PsByN_0dB" with "a" fixed
plot(PsByN_0dB_array,Pout(10,:))
(the 10 is of course arbitrary).
Or you can make a surface plot:
[A,PS] = ndgrid(a_array,PsByN_0dB_array)
surf(A,PS,Pout)

Thanks for explaining different graphs. I really appreciate your help.
