Product of elements in an array
1 view (last 30 days)

I have an array as such (3 5 7 11), I want to find out the unique multiples of these elements i.e.
1) product of pairwise elements -- 15, 21, 33, 35, 55, 77
2) product of three elements -- 105, 385, 231
3) product of four elements -- 1055.
I am currently confused as to how to go about it in an efficient way so that when I extend it to larger number of elements in the array, I don't explode my memory and kill my computer. Any help would be greatly appreciated.
Thanks

For example,
>> x=[3 5 7 11];
>> prod(nchoosek(x,3),2)
ans =
105
165
231
385
