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 .)

这是EMD分解的matlab程序，可以进行imf分解，及求解包络求解(this is EMD program ，it can process imf divide.)

matlab编程 通过设定参数，画出相移布拉格光栅反射谱及色散，反射谱和时延的图象(matlab programming by setting parameters, draw the phase shift image Bragg grating reflection spectrum and dispersion, reflection spectrum and delay)

对AR（4）模型的经典功率谱估计，并与真实功率谱作比较。采用了welch方法，协方差法，burg方法(For AR (4) model of the classic power spectrum estimation, and with true power spectrum for comparison. Welch method using covariance method, burg method)

说明：  matlab入门包括matlab一些函数的编写，有助于初学者了解matlab函数编写方法(matlab)

比较普通的EMd分解的matlab程序，已供初学者学习使用(More common EMd decomposition matlab program, has for beginners learning to use)
