If I have to calculate 10C4(i.e. nchoosek(10,4)),10C3,10C2,10C1, Can I calculate all these four values using one command?
.e.g. in case of factorial If I have to calculate 1! 2! 3! 4! 5!, My command will be n=1:5 followed by factorial(n), which gives required factorials in one command.But in case of combination nchoosek(n,k) does not work the same way.It gives single answer for single values of n and k.If anyone has an alternative solution to my problem, kindly guide me
.In short, I want to calculate more than one combination using single code or single program or single command as in case of factorial above.
Dear Shakeel Khan
see the following video may be help you

Use loop(s) with variables (n,k) , you can make a script ...
Eg: for n....
for k ...
tmp=nchoosek(n,k) ---> store these values
In the link is a small vectorized function I wrote that will do the job for one 'n' and a vector of 'k'.
So, for your example you will need to write:
nCk(10,4:-1:1)
And you will get:
ans =
210
120
45
10

Miss Aparna Murthy you are absolutely right.I used for loop which also worked for me.Thanks to all of you.
