how to plot the sum of series

Considering the following summation, where z=1/2

d=1

how I can plot the p(d), for b=0 to inf or b=0 to 15??

Can anyone send me the code?

So the time I spent to help you is useless, correct? If you’re so afraid of your professor then why would you ask it in the first place?

Original comment by atalo lias:

clear
z=1/2;
d=1;
for b=0:15
    p=((z^(b+d))*exp(-z))/factorial(b+d);
    
end
plot(b,p)

Use cumsum() and then plot(), you need to show some effort to get further help.

[madhan ravi]

z = 1/2;
d = 1;
b = 0:15
p = cumsum((z.^(b+d) .* exp(-z)) ./ factorial(b+d));
plot(b,p)

[madhan ravi]

Replace inf with 1e6.

[madhan ravi]

 z = 1/2;
 d = 1;
 k = 0;
 b = 0:15
 p = zeros(numel(b), 1);
 for k = 1:numel(b)
     p(k) =((z^(b(k)+d))*exp(-z))/factorial(b(k)+d);
 end
 plot(b,cumsum(p))

[madhan ravi]

 z = 1/2;
 d = 1;
 b = 1:15; % start from number other than zero 
 m = 3/2;
 p = zeros(numel(b), 1);
 for k = 1:numel(b)
     p(k) =(((z^(b(k)+d))*exp(-z))/factorial(b(k)+d))*((m^(b(k)+d)*exp(-m))/b(k));
 end
 plot(b,cumsum(p))
