The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of...
利用多态性编程，创建一个square类，实现求三角形、正方形和圆形面积。方法 //抽象出一个共享的类，定义一个函数求面积的公共界面。再重新定义各面积的求面积 //函数，在主类中创建不同类的对象，并求不同形状的面积...
声明一个基类Shape（点）, 在此基础上派生出Rectangle（长方形）和Circle（圆）,这三个类都有GetArea()函数计算对象的面积,构造函数，析构函数等有关函数。再使用Rectangle类创建一个派生类Square(正方形)。并设计创建各种类的对象，调用所有函数。设计函数f(Shap...
