Faster way to compute `nchoosek` in MATLAB

Question

我想找到一个比使用P = nchoosek(1:100,i)更快的代码，它位于一个循环中，并在我的代码中重复了i次。

Answer 1

nchoosek(1:100,10) is absolutely vast, far bigger than any typical machine could hold in memory.

The MATLAB documentation for nchoosek says

C = nchoosek(v,k) is only practical for situations where length(v) is less than about 15 .

You're not really going to be able to do this.

Answer 2

我发现VChoosek(v,k)比nchoosek 。
