【实例简介】

分段线性插值的算法： 1．定义分段线性插值基函数： double inter_Lin_Sec_Base (double X_set[],double x,int n,int k) 其中：X_set[]用来存放节点 的值，x用来传递需求的 值，n用来存放小区间的个数，k表示第 个基函数，返回类型为double； 2．定义拉格朗日插值函数，调用基函数； double inter_inter_Sec_L(double X_set[],double Y_set[],double x,int n) 其中：X_set[] 用来存放节点 的值，Y_set[]用来存放对应于 点的 值，x用来传递需求的 值，n用来存放小区间的个数，返回类型为double； 3．定义主函数，调用插值函数。 这里主要完成数据的输入和输出，功能函数的调用。

4) 创建一个名为Complex的类，进行复数的算术运算。复数的形式为： realpart+imaginarypart*i 用浮点变量表示类的private数据。提供构造函数，能够对所声明的该类对象进行初始化。在不提供初始化值的情况下，该构造函数应包含默认值。针对以下功能，分别提供一个public成员函数。 （1）两个复数相加； （2）两个复数相减 （3）用（a, b）的形式打印复数，其中a为实部，b为虚部。 (4) Create a class called Complex, and perform complex arithmetic operations. Plural form: realpart+imaginarypart* i said private data class with floating point variables. Provide a constructor, the object can be declared for the class is initialized. In the case do not provide initialization values, the constructor should contain default values. For the following functions, which provide a public member function. (A) two complex numbers (2) the subtraction of two complex (3) (a, b) in the form of plural printing, where a is the real part, b is the imaginary part.)
