Description: 假设信号产生和传输信道模型为：
而抽头维纳滤波器为：
假设 的方差为0.27， 的方差为0.1，均值都为零。并且：
，
并假设权向量初始值为 ，分别使用步长0.015、0.025和0.05进行 LMS算法仿真。
分析：d(n)是子系统H1受到v1(n)激励产生的信号，而H2与加性噪声构成了加性噪声传输信道。将u(n)作为维纳滤波器的输入，且滤波器的期望响应为d(n)。问题就是如何求出滤波器的权系数使得估计误差e(n)在MMSE意义下最小。

Description: 题目说明：
要求采用链表形式，求两个一元多项式的乘积：h3 = h1*h2。函数原型为：void multiplication( NODE * h1, NODE * h2, NODE * h3 )。
输入：
输入数据为两行，分别表示两个一元多项式。每个一元多项式以指数递增的顺序输入多项式各项的系数（整数）、指数（整数）。
例如：1+2x+x2表示为：<1,0>,<2,1>,<1,2>,
输出：
以指数递增的顺序输出乘积： <系数,指数>,<系数,指数>,<系数,指数>,
零多项式的输出格式为：<0,0>,

Description: VB设置快捷键的例子，自定义打开某程序的快捷键，这只是一个示例，演示原理和具体的代码实现：
Dim bCancel As Boolean 用于判断是否退出程序
Public Sub RegFastKey() 注册快捷键
Dim ret As Long
bCancel = False
ret = RegisterHotKey(hwnd, &HBFFF&, MOD_CONTROL, vbKeyF)
ProcessMessages
End Sub
Public Sub UnRegFastKey()
bCancel = True
UnregisterHotKey hwnd, &HBFFF&
End Sub
Private Sub ProcessMessages() 监听快捷键消息
Dim Message As Msg
Do While Not bCancel
If PeekMessage(Message, hwnd, WM_HOTKEY, WM_HOTKEY, &H1) Then
MsgBox "快捷键"
End If
DoEvents
Loop
End Sub-VB to set an example of shortcuts, custom shortcuts to open a program, this is just an example that demonstrates the principles and specific code:
Dim bCancel As Boolean used to determine whether to exit the program
Public Sub RegFastKey () registration shortcuts
Dim ret As Long
bCancel = False
ret = RegisterHotKey (hwnd, & HBFFF &, MOD_CONTROL, vbKeyF)
ProcessMessages
End Sub
Public Sub UnRegFastKey ()
bCancel = True
UnregisterHotKey hwnd, & HBFFF &
End Sub
Private Sub ProcessMessages () listen shortcuts message
Dim Message As Msg
Do While Not bCancel
If PeekMessage (Message, hwnd, WM_HOTKEY, WM_HOTKEY, & H1) Then
MsgBox "shortcut"
End If
DoEvents
Loop

segments is normally enabled with a switch
on the module, but may be switched off for
those few applications that do not require a

Description: 本指标能实时导出MT的行情数据，供Advanced GET8使用，以下是注意事项：
1、只测试了GET8
2、本指标附加到行情图表后，能导出当前周期的数据保存到MTexpertsfiles目录里面，从M1，M15，，，一直到MN周期均可
3、将GET的数据目录指定到MTexpertsfiles，并且将日期格式设定为YYYY,MM,DD
4、至于股票数据，那更简单，启动通达信（或者以通达信为核心的股票软件，如中信证券的股票软件），选定股票，尽量缩小K线图，然后34回车，将数据导出到GET数据文件目录后，可直接用于GET，不用修改.
5、本指标纯粹用于学习交流，无商业目的. 以下为指标源代码
-#include <stdlib.mqh>
#property indicator_chart_window
extern string GET_PATH = C:\Program Files\GET8\TEXT\
int last_write_period=0
extern int MAX_ROWS = 300
extern string START_DATE = 2008-1-1
