BINOMIALPDF : Binomial Probability Density function

BINOMIALPDF Returns the probability that X = k in sample n.

Very easy function to use that helps statisticians solve all kinds of problems.
The function does not need the Statistics Toolbox. I have included the BINOMIND function which this one calls but you can
download it separately if you like. I uploaded it to MATLAB Central as well.

EX1: binomialpdf(40,6,0.1,'exact') % = bpdf(X=6) where 0.1 = 10%
% ans = 0.106756244747289

% EX2: binomialpdf(11,2,0.1,'atmost') % = bpdf(X=0)+bpdf(X=1)+bpdf(X=2)
% ans = 0.910438149150000

% EX3: binomialpdf(10,2,0.1,'atleast')% = bpdf(X=2)+...+bpdf(X=10)
% ans = 0.263901070900000
