Median

This function calculates the median value of the supplied 1- or 2-d array. The function sorts the array values: if the number of elements is odd, the central element of the sorted list is returned; if even, the element in the lower of the two central elements is returned.

  interface median
    real(single) function medianVector(array)
      real(single), intent(in) :: vector(:)
    end function medianVector

    real(single) function medianArray(array)
      real(single), intent(in) :: array(:,:)
    end function medianArray
  end interface
