How to call VChooseK function?

I tried to use vchoosek(v, k). But get the error message saying "undefined function or variable". Can anybody tell me how to call this function correctly? Thank you!

Did you download it to a place where Matlab can see it?

Hello Ruini,

You need to download vchoosek which can be found in MATLAB Central's File Exchange and then add it to MATLAB's path. Please follow this link to download:

Alternatively, you can explore and use MATLAB's built-in nchoosek function for similar functionality. Please follow the below link to know more about the same:

I hope it helps!
