You can save results of nchoosek to a table to prevent repeated evaluation of the function, also an implementation of binomial coefficients provided: %binomial coefficients function nk=nchoosek2 (n, k) if n-k > k nk = prod ( (k+1:n) .* prod ( (1:n-k).^ (-1/ (n-k)))); else nk = prod ( (n-k+1:n) .* prod ( (1:k).^ (-1/k)) ) ; end end … WebAll combinations of v, returned as a matrix of the same type as v. Matrix C has k columns and n !/ ( ( n – k )! k !) rows, where n is length (v). Each row of C contains a combination of k items chosen from v. The elements in each row of C are listed in the same order as they appear in v. If k > numel (v), then C is an empty matrix.

Here, the distribution parameters n and p are scalars. Use the binornd function to generate random numbers from the binomial distribution with 100 trials, where the probability of success in each trial is 0.2. The function returns one number. r_scalar = binornd (100,0.2)
