zzy-MATLAB

关于MATLAB很基础，但是不错的一本电子书的PPT，适合初学者。(Very foundation, suitable for beginners. A good book.)

this is a document on digital image processing and fingure print classification as well..

Impedance Spectroscopy

The morphology operation to read the image and convert the rgb2gray, and convert in to the binaring the input image.Adding the binary noise to the image next the input image to make text in white and background in black. Next do the two operation dilation and erosion.

说明：  用matlab语言实现单频脉冲信号（CW）的时域波形、频域图像、模糊度图。(The time-domain waveform, frequency-domain image and ambiguity map of single frequency pulse signal (CW) are realized by MATLAB.)

给出了kf ekf ukf upf的matlab源程序，通过用户自己修改可以方便的实现各种系统辨识。(Given kf ekf ukf upf the matlab source code through the user' s own can be easily modified to achieve a variety of system identification.)

This is a code for periodic impusive noise in ofdm based power line communications. It is implemented in matlab.

emd和eemd可用于信号去噪，提取瞬时频率。(emd and can be used to signal de-noising eemd extracting instantaneous frequency.)
