Pulse_Width_Modulator

again numerical computing using matlab environment

说明：  目标跟踪,利用自我学习的子空间，此算法的最大特点是利用了粒子滤波，并且速度快(incremental basis visual tracking)

各种随机信号的自相关函数和功率谱密度函数、画图(Autocorrelation function and power spectral density function of a variety of random signals, drawing)

说明：  最小二乘支持向量机,是支持向量机算法的一种改进版本——即最小二乘支持向量机(Least Squares Support Vector Machine)(Least squares support vector machine)

说明：  对一个16元等距线阵，间距为半个波长，空间5个相互独立信源从不 同方向入射，信噪比分别为30、25、20、15、5dB。采用MUSIC方法估 计其空间入射方向(For a 16 element equidistant linear array, the spacing is half a wavelength, and five independent sources are incident from different directions. The SNR is 30, 25, 20, 15 and 5dB respectively. Music method is used to estimate the spatial incident direction)

用模最大值法提取小波脊，该例中又两条小波脊，所以是多脊提取。同时又施加惩罚函数，控制lamda的值，可以得到较为平滑的小波脊。( using maximum modulus extract wavelet ridge, the case has two wavelet ridge, it is a multi-ridge extraction. At the same time to impose the penalty function to control the value of lamda,the extracted ridge can be relatively smooth .)
