可以改变信噪比 分析在不同信噪比下 高斯白噪声中正弦信号的高阶谱情况 用于检测信号()

此功能会产生这是一个“搁置”的设计为一个单一的IIR双二阶系数。 wierldy不够，这种过滤器的类型是不标准的Matlab的滤波器设计工具箱的一部分。这些是常用的过滤器是创建一个图形均衡器的音频信号处理。(This function will generate the coefficients for a single IIR biquad that is a "shelving" design. Wierldy enough, this filter type is not part of the standard Matlab filter design toolbox. These filters are commonly used is audio signal processing to create a graphic equalizer. )

matlab的simulink的简单介绍和一些例子，适合初学者(the matlab simulink the brief and some examples, suitable for beginners)

ROI area identification, iteration, MCAA, zbthresh This program is simple, everyone can learn under

The recent development of a meshless method by using radial basis functions will be reported in this talk. Application to both multivariate interpolation and solving partial differential equations have demonstrated the spectral convergence of the method for some particular radial basis functions like multi quadric. This talk will also discuss some of the recent proposed techniques for solving the ill-conditioning problem resulted from solving the full resultant matrix.

两点边值问题，微分方程数值解法，数值分析作业(Boundary Value Problems, Numerical Solution of Differential Equations)

数学方法是部分子空间法，有小波分析的盲信号处理，小波包分析提取振动信号中的特征频率。( Mathematics is part of the subspace, There Wavelet Analysis Blind Signal Processing, Wavelet packet analysis to extract vibration signal characteristic frequency.)

MATLAB实现语音去噪处理，测试已经通过了(Speech Denoising MATLAB realize treatment, testing has been adopted)

说明：  利用matlab语言编写的水下简正波分析程序，可计算P(Matlab language use underwater normal wave analysis procedures, calculate P)

用matlab实现的3Dplot绘制例子程序。(draw 3Dplot using matlab)
