given a set of numbers, such as ,1,5,4,2, we can sort it and the result is 5
,4,2,1 by the descending order.
but if given a set of vectors, how to sort them,
for example
a1={1,1,1,1,4}
a2={2,1,4,3,2}
a3={3,2,4,2,1}
how to sort a1, a2, and a3?

Right. LZ must define a function (rule) to compare two vectors. The
implementation depends on your programming language,but it should be fairly
easy to do it using some libraries/functions, e.g. the qsort function in C,
if the comparison is well defined.

How to sort a generic List
After reading this post from Steven Smith I thought I should write something about it.
Sorting a generic List is pretty straightforward if you know how to do it. With C# 2.0, anonymous
methods come at hand, as well as the little known Comparison delegate (check out this post for more
information about this class as well as other useful classes new to C# 2.0).
Ok, let's suppose we have a product class (let me save some space by using C# 3.0 syntax).
-----
Public Class Product
Implements IComparable(Of Product)
' Methods
Shared Sub New()
Product.PriceComparison = Function (ByVal p1 As Product, ByVal p2 As
Product)
Return p1.price.CompareTo(p2.price)
End Function
Product.IDComparison = Function (ByVal p1 As Product, ByVal p2 As
Product)
Return p1.id.CompareTo(p2.id)
End Function
End Sub
Public Sub New(ByVal id As Integer, ByVal prodName As String, ByVal
price As Decimal)
Me.id = id
Me.prodName = prodName
Me.price = price
End Sub
Public Function CompareTo(ByVal other As Product) As Integer
Return Me.ProductName.CompareTo(other.ProductName)
End Function
Private Shared Sub Main()
End Sub
Public Overrides Function ToString() As String
Return String.Format("Id: {0} Name: {1} Price: {2}", Me.id, Me.
prodName, Me.price)
End Function
' Properties
Public Property ProductID As Integer
Get
Return Me.id
End Get
Set(ByVal value As Integer)
Me.id = value
End Set
End Property
Public Property ProductName As String
Get
Return Me.prodName
End Get
Set(ByVal value As String)
Me.prodName = value
End Set
End Property
Public Property UnitPrice As Decimal
Get
Return Me.price
End Get
Set(ByVal value As Decimal)
Me.price = value
End Set
End Property
' Fields
Private id As Integer
Public Shared IDComparison As Comparison(Of Product)
Private price As Decimal
Public Shared PriceComparison As Comparison(Of Product)
Private prodName As String
End Class

depending on your rules. For example, you can sort by the length of vectors,
a1 = 1^2 + 1^2 + 1^2 + 1^2 + 4^2, etc. You can also look for their spatial
distribution. We have many software for high-content screenings that can do
it. It's not sorting though

Exactly the same here (PD 9/2007, RD 11/2011) and still "initial review". At
least you will get interview, after which you will get greened soon. My
status has been unchanged since "On November 2, we received your..."
Ridiculous!
Don't worry -- it's your turn soon. Bless us all!
