多项式曲线拟合 任意介数 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） 设计和编写代表矩阵的Matrix类。该类包括矩阵行列数变量int rows和int cols，矩阵数据数组double data[][]，构造方法Matrix()、Matrix(int rows,int cols)、Matrix(int rows,int cols,double data[][])，获取某元素值的方法getData(int row,int col)，设置某元素值的方法setData(int row,int col,double value)，计算两个矩阵的乘积的方法multiply(Matrix m)以及toString()等内容。

（1） 实现一个Point类，该类包含表示坐标的两个int型变量x、y，构造方法Point()和Point(int xx, int yy),返回x值和y值的int getX()和int getY()方法，计算两点间距离的double distance(Point)方法。其中计算平方根用Math.sqrt()方法。 （2） 实现一个Circle类，该类包含表示圆心的Point型变量center，表示半径的int radius变量，以及构造方法Circle()、Circle(int xx,int yy,int r)、Circle(Point c,int r)，返回周长和面积的int perimeter()、double area()方法，返回两个圆是否为同一个圆（返回0）、同心圆（返回1）、相交的圆（返回2）、分离的圆（返回3）、包含的圆（返回4）等关系的int relation(Circle c)等方法。PI值可以用Math.PI常量。 （3） 实现测试上述两个类的ClassTest类。该类在main方法中分别创建若干个Point对象和Circle对象，并调用相关方法，输出方法的返回值，验证其正确性。 （4） 将Point类、Circle类和主类的包名分别调整为p1、p2、p3，并重新运行，验证是否运行正确。

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说明文档。配置文件init部分声明那些用于建立远程bean和在方法调用中转换bean的类.这部分是可选择性配置的,多数情况下可以不必使用它,如果你想定义一个新的creator或者converter那么就必须在部分中声明,but do double check on the ones that are currently available first.
