Undefined function 'combntns' for input arguments of type 'double'.

Hi all,

i looking any matlab function that can calculate 'combination' such as (3 C 2) =3.

There is a matlab function for (5 C 3)=10, but returns errors as following. Please help me to suggest

combos = combntns(1:5,3)

error:
Undefined function 'combntns' for input arguments of type 'double'.

the function is part of the Mapping Toolbox. Use nchoosek instead.
