function coefficients = binomialCoeff(n,k)
coefficients = zeros(numel(n),numel(k)); %Preallocate memory
columns = (1:numel(k)); %Preallocate row and column counters
rows = (1:numel(n));
%Iterate over every row and column. The rows represent the n number,
%and the columns represent the k number. If n is ever greater than k,
%the nchoosek function will throw an error. So, we test to make sure
%it isn't, if it is then we leave that entry in the coefficients matrix
%zero. Which makes sense combinatorically.
for row = rows
for col = columns
if k(col) <= n(row)
coefficients(row,col) = nchoosek(n(row),k(col));
