>> help binocdf

 BINOCDF Binomial cumulative distribution function.
    Y=BINOCDF(X,N,P) returns the binomial cumulative distribution
    function with parameters N and P at the values in X.
 
    The size of Y is the common size of the input arguments. A scalar input  
    functions as a constant matrix of the same size as the other inputs.    
 
    The algorithm uses the cumulative sums of the binomial masses.
