自己写的一个锁相环程序，希望对大家有所帮助(A phase-locked loop to write their own procedures, we hope to be helpful)

模拟脉冲在光纤中传输时色散对其的影响,通过作图形象地说明脉冲时域和频谱的演化(the dispersion effect of pulse propagating in fiber)

bidimentionnal empirical mode decomposition

fingerprint image processing such as sungularity and core point detection

模拟二维空间中TM波的传播过程，当执行TM波的时域有限差分格式时，就能在网格空间中模拟TM波的传播过程。(simulated two-dimensional space TM wave propagation process, the implementation of the TM-wave finite-difference time-domain format, Grid will be in space simulation TM wave propagation process.)

实现了对语音信号的FFT处理，用matlab(Realization of the speech signal FFT processing, using matlab)

采用Matlab实现反馈神经网络构建，共有15个例子。(Feedback is realized by using the Matlab neural network building.)

matlab code to plot figure inside figure (main and inset)

actually this is a matlab file to compress an image.

In order to capture the spatial dependence of gray-level values which contribute to the perception of texture, a 2d dependence matrix known as a gray-level co-occurrence matrix is extensively used in texture analysis.So, this is a code that calculate a co-occurrence matrix of the image and return the following features: ENERGY, CONTRAST, CORRELATION and HOMOGENEITY.
