多項式曲線擬合 任意介數 Purpose - Least-squares curve fit of arbitrary order working in C++ Builder 2007 as a template class, using vector<FloatType> parameters. Added a method to handle some EMathError exceptions. If do NOT want to use this just call PolyFit2 directly. usage: Call PolyFit by something like this. CPolyFit<double> PolyFitObj double correlation_coefficiant = PolyFitObj.PolyFit(X, Y, A) where X and Y are vectors of doubles which must have the same size and A is a vector of doubles which must be the same size as the number of coefficients required. returns: The correlation coefficient or -1 on failure. produces: A vector (A) which holds the coefficients.

（1） 設計和編寫代表矩陣的Matrix類。該類包括矩陣行列數變量int rows和int cols，矩陣數據數組double data[][]，構造方法Matrix()、Matrix(int rows,int cols)、Matrix(int rows,int cols,double data[][])，獲取某元素值的方法getData(int row,int col)，設置某元素值的方法setData(int row,int col,double value)，計算兩個矩陣的乘積的方法multiply(Matrix m)以及toString()等內容。

（1） 實現一個Point類，該類包含表示坐標的兩個int型變量x、y，構造方法Point()和Point(int xx, int yy),返回x值和y值的int getX()和int getY()方法，計算兩點間距離的double distance(Point)方法。其中計算平方根用Math.sqrt()方法。 （2） 實現一個Circle類，該類包含表示圓心的Point型變量center，表示半徑的int radius變量，以及構造方法Circle()、Circle(int xx,int yy,int r)、Circle(Point c,int r)，返回周長和面積的int perimeter()、double area()方法，返回兩個圓是否為同一個圓（返回0）、同心圓（返回1）、相交的圓（返回2）、分離的圓（返回3）、包含的圓（返回4）等關系的int relation(Circle c)等方法。PI值可以用Math.PI常量。 （3） 實現測試上述兩個類的ClassTest類。該類在main方法中分別創建若干個Point對象和Circle對象，并調用相關方法，輸出方法的返回值，驗證其正確性。 （4） 將Point類、Circle類和主類的包名分別調整為p1、p2、p3，并重新運行，驗證是否運行正確。

This application includes a demo server and client program. You could write your own server launcher and client application by using the SimpleScreenCaptureServer class and the SimpleRemoteScreenCaptureClient class. Usage: 1. Type the following command to launch the server program. java -jar SimpleCaptureScreenServerDemo.jar portnumber 2. Type the following command to launch the client program. It s a swing-based UI. java -jar RemoteScreenCaptureClientUI.jar 3. Select Run/Connect menu. Input your server address and port number. You could just double-click on the RemoteScreenCaptureClientUI.jar to launch the client program if you are using Windows. This program is written just for fun. :lol: :lol: :lol:

dwr.xml說明文檔。配置文件init部分聲明那些用于建立遠程bean和在方法調用中轉換bean的類.這部分是可選擇性配置的,多數情況下可以不必使用它,如果你想定義一個新的creator或者converter那么就必須在部分中聲明,but do double check on the ones that are currently available first.
