帮助实现N阶自适应滤波器的滤波原理，通过读入一组信号并对其进行去噪的处理，通过频谱图看出其良好的滤波效果从而发现N阶自适应滤波器的优点(N-order adaptive filter to help achieve the principle of filtering, by reading into a signal and its de-noising processing, through the spectrum to see their good filtering effect to discover the advantages of adaptive filter of order N)

this is matlab code to solve tveq_newton problem!!!

在MATLAB中求图像纹理特征，线性调频脉冲压缩的Matlab程序,滤波求和方式实现宽带波束形成。( In the MATLAB image texture feature, LFM pulse compression of the Matlab program, Filtering summation way broadband beamforming.)

polarPcolor是一个函数,旨在用极坐标表示伪彩色图,与径向网格允许数据的一个简单的演讲。它非常适合平面位置显示器(PPI)扫描雷达为例。我们的目标是提供信息的极坐标给定变量Z。(polarPcolor is a function that aims to represent a pseudocolor plot in polar coordinates, with a radial grid to allow an easy lecture of the data. It is well suited for Plan Position Indicator (PPI) scan for radar for example. The goal is to provide information about the polar coordinate of a given variable Z. )

应用matlab产生用正弦信号调制的模拟PPM信号，并给出了功率谱密度(Matlab sinusoidal signal generated by application of the analog PPM signal modulation, and gives the power spectral density)

用matlab编写的人脸检测程，效果非常高，附有文章以理解。(Matlab prepared with face detection process, the effect is very high, in order to understand the article attached.)

说明：  用MATLAB编写的运用Monte Carlo method数值积分的实例程序。可供初学者参考学习！(TETRAHEDRON_MONTE_CARLO is a MATLAB library which estimates the integral of a function over a tetrahedron using the Monte Carlo method. The library makes it relatively easy to compare different methods of producing sample points in the tetrahedron, and to vary the tetrahedron over which integration is carried out. )
