计算输入信号的功率谱密度和估计输入信号带宽并绘图(Evaluation of the single-sided ESD and frequency bandwidth)

说明：  这是黑龙江大学自控理论专业同学在最优估计课程当中用matlab编写的带遗忘因子的最小二乘法!(This is the theory of controlled Heilongjiang University students in professional courses optimal estimate prepared by using Matlab forgotten factor with the least squares method.)

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal

录入程序代码，并对该实验代码进行调试，检查程序代码中的语法和语义错误。 编写函数f（x）的代码如下： Romberg算法¨ function z=f(x) if (x~=0) z=sin(x)/x else z=1 end 备注：在实验代码中，首先输入必要的变量的值如下： a=0 b=1 tol=1e-8 待查询检查通过，开始输入执行代码 设置格式format short g查看u的值和sin（u）的值： (Input program code, and debugging code for the experiment to check the program code in the syntax and semantic errors. The preparation of a function f (x) of the code is as follows: Romberg algorithm ¨ function z = f (x) if (x ~ = 0) z = sin (x)/x else z = 1 end Note: In the experimental code, First, enter the necessary value of the variable is as follows: a = 0 b = 1 tol = 1e-8 pending inquiries, checking through, began to enter the implementation of the code format format short g see u, values and sin (u) values:)

ssb调制信号，适合matlab仿真使用，功能不错，希望能帮到大家(ssb modulation signal, suitable for simulation using matlab, functions well, hope to help you)
