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.)

例4:在sinc(t)信号中叠加噪声,分析对应频谱
fs=100 采样频率,必须大于两倍基带信号最高频率
ts=1/fs 采样时间间隔
T=2 时间窗大小

x=x+0.1*randn(1,N)
x=awgn(x,-10, measured )

if mod(N,2)~=0
N=N-1
end
f=linspace(0,fs/2,N/2)
plot(f,abs(y(1:N/2))*2/N)
