Binomial coefficient or all combinations
C = nchoosek(n,k)
k are nonnegative integers, returns . This is the number of combinations of things taken at a time.
C = nchoosek(v,k),
v is a row vector of length
n, creates a matrix whose rows consist of all possible combinations of the elements of
v taken at a time. Matrix
C contains rows and columns.
nchoosek(2:2:10,4) returns the even numbers from two to ten, taken four at a time:
This function is only practical for situations where
n is less than about 15.
