Matlab_Code

Matlab实现：erlang 公式，并且几种模式下的实现(erlangB and erlangC/engset model matlab)

说明：  加循环前后缀和升采样程序，插入循环前后缀是将每个OFDM符号的前32个数据放到符号尾部，将每个OFDM符号的后32个数据放到符号头部，升采样是通过中间插零的方式实现(Cycle before adding the suffix and lift sampling program, insert the loop before the suffix is ??the first of each OFDM symbol data into the symbolic end of 32, after each OFDM symbol data into the symbols of 32 head or through the middle of the sampling way to achieve zero insertion)

gammatone滤波器，模拟人耳的滤波功能，处理由麦克风接收到的声音信号，获得其特征参数。(gammatone filter to simulate the human ear filtering, processing the received voice signal from the microphone to obtain the characteristic parameters.)

一个二维的fdtdc++编写的程序，较完整，带有pml边界条件。感兴趣的可以下载看看。(A two-dimensional fdtdc++ preparation procedures, more complete, with pml boundary conditions. Interested can download to see.)

说明：  主要用于故障诊断的神经网络预测KPCAcontourmap代码文件(Neural Network Prediction KPCAcontourmap Code File for Fault Diagnosis)

1. 选择一个wav文件作为分析的对象，对该信号进行读取（使用wavread函数）； 2. 音乐信号的频谱分析：首先画出信号的时域波形，然后对信号进行频谱分析得到信号的频谱特性。 3. 设计一组数字滤波器并画出各个滤波器的频率响应 (Filter)

说明：  matlab实用程序，大概100个，写成txt文档(matlab utility, about 100, written in txt file)

简支梁受各种力综合作用的剪力，弯矩计算及图形绘制(By the comprehensive function of simply supported beam power of the shear and moment calculation and graphics)

A simple script that simulates the evolution of a system subjected to random thermal fluctuations(based on Ken Elder s 1993 paper: "Langevin simulations of nonequilibrium phenomena")

说明：  在处理数据的时候我们经常要算各个区间的频数,但是在matlab中没有这样的命令.当数据比较大的时候自己数就比较麻烦,这里编了个小程序,(Handle data in a time when we often have to count the frequency of each interval, but there is no such matlab in command. When the data when the relatively large number of on its own is too much trouble here编了个small procedures,)
