pi/4DQPSK调制解调程序，解调使用的是差分解调算法。(pi/4 DQPSK modulation and demodulation)

LDA知识的讲解，浅显易懂，便于学习，还有对LDA模型的建立的说明以运用(LDA knowledge to explain, easy to understand, easy to learn, as well as the establishment of LDA model description to use)

matlab 地震 速度分析 自写的matlab源程序(matlab Velocity analysis)

画出电基本阵子的仿真图 用matlab实现(Recently drawn the basic electrical diagram of the simulation using matlab realize)

说明：  产生一个4096点的正弦加白噪声序列，且产生该序列的幅度谱(Produce a 4096 point increase in white noise sinusoidal sequence, and generate the sequence of the amplitude spectrum)

QPSK调制解调误码率及误符号率，相干解调，输出的bitber是误码率，symber是误符号率(QPSK demodulator BER and misuse of the symbol rate, coherent demodulation, the output is bitber BER, symber mistakenly Symbol Rate)

说明：  这是基于matlab的dea程序，包括交叉对抗型模型(Procedures based on matlab' s dea)

计算兄弟数，平时练习题，算法比较笨，欢迎指教(Calculate the number of brothers, usually exercises, algorithm is stupid, please advise)

利用matlab实现了人脸检测的功能，主要是利用人脸颜色特征向量。(Matlab face detection function, face color feature vector.)

处理lasso regression。 使用stochastic Markov property。(Algorithm for solving the Lasso problem: 0.5* (y- X*beta) *(y- X*beta)+ lambda* ||beta||_1 where ||beta||_1 is the L_1 norm i.e., ||beta||_1 = sum(abs( beta )) We use the method proposed by Fu et. al based on single co-ordinate descent. For more details see GP s notes or the following paper: Penalized Regressions: The Bridge Versus the Lasso Wenjiang J. FU, Journal of Computational and Graphical Statistics, Volume 7, Number 3, Pages 397?416, 1998 )
