Version:
    Last Modified: January 9, 2017

    Finds the median value of a sequence by sorting the values in the sequence and averaging the middle element(s) of the sorted array.

    x

    Input sequence.

    If x is empty, median is NaN.

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    median

    Calculated median value of the input sequence.

    error out

    Error information. The node produces this output according to standard error behavior.

    Finding the Median Value of a Sequence

    The node finds median using the following equation.

    median = { s i if n is odd 0.5 ( s k 1 + s k ) if n is even

    where

    • n is the number of elements in the input sequence x
    • s is the sorted sequence of x
    • i = n 1 2
    • k = n 2

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
