    The combntns function has been removed. Use the nchoosek function instead. For more information, see Compatibility Considerations.

    Syntax

    C = combntns(v,k)

    Description

    example

    C = combntns(v,k) returns all possible combinations of the set of values v, given combinations of length k.

    Examples

    collapse all

    Find all possible combinations of five numbers taken three at a time.

    v = 1:5;
C = combntns(v,3)
    C =

     1     2     3
     1     2     4
     1     2     5
     1     3     4
     1     3     5
     1     4     5
     2     3     4
     2     3     5
     2     4     5
     3     4     5

    Input Arguments

    collapse all

    Set of all choices, specified as a vector.

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | char
    Complex Number Support: Yes

    Number of selected choices, specified as a nonnegative integer scalar. This argument can be any numeric type, but must be real.

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

    Output Arguments

    collapse all

    All combinations of v, returned as a matrix of the same data type as v. The number of columns in C is the same as the value of k.
