The closest you can get is the binomial distrbution, specifically the binopdf function (in the Statistics Toolbox).
— EDIT —
Your Subject says ‘pdf’ and your Question says ‘cdf’. This uses ‘cdf’.
Experiment with this to get the result you want:
% Bernoulli CDF Plot
p = 0.5; % Probability Of Success
N = 10; % Maximum Number OF Trials
Nv = [1:N];
C = binocdf(1, Nv, 0.5);
figure(1)
plot(Nv, C)
grid
