将灰度图转化为lbp图谱，邻域选择为圆域，半径为r，邻域内点的数目为p。(Lbp map will be converted to grayscale, neighborhood circle domain, the number of radius r, neighborhood point is p.)

matlab实现菲涅耳全息图,简单明了，很有用.自己整理的,可以直接运行。(matlab achieve the Fresnel hologram, simple and useful. collate their own, and can be directly run.)

(2,1,2)卷积码编硬译码matlab程序,适合学习信道与编码的初学者((2,1,2) convolutional code encoding hardware decoding matlab program for learning channel coding for beginners)

the tranformation from X,Y Z to geodetic latitude and longitude

本文分析了语音数字信号的采集来源以及其预处理。通过实例，利用Matlab对语音信号进行时频变换与分析，同时构造一个固定频率的干扰信号，对两个信号进行合成，设计数字滤波器，实现对语音信号的F IR、IIR滤波处理，最后在时域和频域中对信号进行分析比较。(This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.)

code for ofdm, good for study

产生不同频率、幅度的正弦波信号，叠加后，设计低通、带通滤波器进行正弦信号的谱分析及提取。(The sine wave signals with different frequencies and amplitudes are generated. After superposition, the low-pass and bandpass filters are designed for spectrum analysis and extraction of sinusoidal signals.)

这个程序可以演示关于哲学家就餐的问题，对于理解线程的相互等待有很好的作用(This procedure can be demonstrated on the Dining Philosophers problem, each thread to wait for understanding the role of good)

LLE是一种很常用的降维方法，这是用matlab实现的(LLE is a very popular dimensionality reduction method, the code implemented using matlab)
