本函数用于生成自然数环形矩阵，从里到外是0>n.编写者中北大学09级学生闫**。(This function is used to generate a circular matrix of natural numbers, 0> n from the inside to out. Yan** 09 North University students is the writers has full copyright. )

惯性导航，利用惯性元件（加速度计）来测量运载体本身的加速度，经过积分和运算得到速度和位置，从而达到对运载体导航定位的目的。组成惯性导航系统的设备都安装在运载体内，工作时不依赖外界信息，也不向外界辐射能量，不易受到干扰，是一种自主式导航系统。(Inertial navigation, to measure the carrier itself acceleration Inertial element (accelerometer), through integration and operation to get the speed and position, so as to achieve the purpose of vehicle navigation. Inertial navigation systems equipment components are installed in the carriage of the body, does not rely on external information work, not to the outside world-radiation energy, less susceptible to interference, it is an autonomous navigation system.)

matlab中是没有GMDH神经网络工具箱的，好多书籍中也没有代码，本人编写了一个，望对读者有用，记者把里面的函数分开写成一个个的m文件(There is no GMDH neural network toolbox of matlab, a lot of books in no code, I wrote a, hope is useful to the reader, the reporters to separate the function inside the written one m files)

说明：  利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。(Bilinear transformation method is used to design a cascade elliptic IIR filter, for a period of noise speech signal filtering denoising processing and according to the waveform and spectrum analysis of filtering performance before and after filtering. This course design simulation platform for the MATLAB7.0, development tools is M language programming. First under Windows tool to record a voice signal, a tape recorder and deliberately added a single frequency noise, and then the signal to determine the added noise frequency spectrum analysis, and design the filter for filtering denoising processing, finally compared before and after the waveform and spectrum of filtering and analyzed. )
