数组定义问题
大家好：
问题是这样的：我想编一个K均值的聚类算法，如何定义这样的一个数组，它包括19个记录，但每个记录又由4个变量组成，见下面数据。
month X1 X2 X3 X4
1 11.03 50.30 11.81 11.27
2 5.47 19.30 5.20 7.18
3 3.58 9.85 3.14 2.11
4 2.01 4.17 1.47 1.58
6 2.13 5.65 1.04 2.11
8 2.06 1.74 .17 1.57
10 1.63 2.04 1.04 1.46
12 1.17 1.60 .89 .76
15 1.03 2.34 .53 .89
18 .69 1.33 .48 .58
24 .77 1.41 .52 .42
30 .59 1.25 .30 .14
36 .65 1.19 .49 .38
42 .51 .93 .16 .25
48 .73 1.13 .35 .55
54 .53 .82 .16 .34
60 .36 .52 .19 .21
66 .52 1.03 .30 .55
72 .34 .49 .18 .16

请高手提点一下，把里面的变量能不能定义成结构呀？。。。。。。在线等

I suggest you to define an arrylist object, and then you can use it's Add method to add your object before you create a object .

ArrayList list = new ArrayList();
list.Add(yourobject);


you must define the special class/struct for you data model.

public struct struct1
{
public double f1;
public double f2;
public double f3;
public double f4;
}
struct1[] A = new struct1[19];
A[i].f1 = XXX;
A[i].f2 = XXX;
A[i].f3 = XXX;
A[i].f4 = XXX;
[解决办法]

C# code

struct data{    public double month;    public double X1;    public double X2;    public double X3;    public double X4;    public data(double month, double x1, double x2, double x3, double x4)    {        this.month = month;        this.X1 = x1;        this.X2 = x2;        this.X3 = x3;        this.X4 = x4;    }}private void abc(){    List<data> list = new List<data>();    list.Add(new data(1, 11.03, 50.30, 11.81, 11.27));    list.Add(new data(2, 5.47, 19.30, 5.20, 7.18));    list.Add(new data(3, 3.58, 9.85, 3.14, 2.11));    list.Add(new data(4, 2.01, 4.17, 1.47, 1.58));    list.Add(new data(6, 2.13, 5.65, 1.04, 2.11));    list.Add(new data(8, 2.06, 1.74, 0.17, 1.57));    list.Add(new data(10, 1.63, 2.04, 1.04, 1.46));    list.Add(new data(12, 1.17, 1.60, 0.89, 0.76));    list.Add(new data(15, 1.03, 2.34, 0.53, 0.89));    list.Add(new data(18, 0.69, 1.33, 0.48, 0.58));    list.Add(new data(24, 0.77, 1.41, 0.52, 0.42));    list.Add(new data(30, 0.59, 1.25, 0.30, 0.14));    list.Add(new data(36, 0.65, 1.19, 0.49, 0.38));    list.Add(new data(42, 0.51, 0.93, 0.16, 0.25));    list.Add(new data(48, 0.73, 1.13, 0.35, 0.55));    list.Add(new data(54, 0.53, 0.82, 0.16, 0.34));    list.Add(new data(60, 0.36, 0.52, 0.19, 0.21));    list.Add(new data(66, 0.52, 1.03, 0.30, 0.55));    list.Add(new data(72, 0.34, 0.49, 0.18, 0.16));}
