带通滤波实现各种滤波窗口的带通滤波功能，汉宁窗(bandpass filter)

symbol error rate for QPSK(4-QAM) modulation

采用AHP方法，采用比较矩阵，对各层目标参数进行权重分配(AHP method using the target parameters weight distribution)

说明：  读、写surfer文本的GRD格式的matlab程序，适合不需要插值的数据读写，比surfer自带的数据网格化功能处理的速度要快几十倍、甚至上百倍，可以处理大容量数据。(Reading and writing text surfer GRD format matlab program for reading and writing data without interpolation, the grid than the surfer' s own data processing capabilities several times faster, or even a hundred times, can handle large amounts of data.)

Plots the AVaR versus different confidence levels given a Profit-Loss vector. It calculates AVaR assuming a Gaussian distribution for the P/L vector.

这是一本研究目标定位跟踪的学习手册（在雷达，声纳，无线传感器网络领域等），采用的方法有最小二乘/极大似然，卡尔曼滤波，蒙特卡洛，粒子滤波等方法，更是很多读者需要的是里面有大量的仿真实例和程序代码，并配以中文注释，读者可以结合书中的原理和公式，对程序有进一步的理解。也适合很多读者在已有的代码的基础上对算法进行改进。(This is a study targeting the learning manual tracking (radar, sonar, wireless sensor networks, etc.), using the least squares method/maximum likelihood, Kalman filtering, Monte Carlo, particle filtering methods , but many readers need is there are a large number of simulation examples and program code, and with Chinese notes, the book the reader can combine the principles and formulas, a better understanding of the program. Also suitable for many readers on the basis of the existing code to improve the algorithm.)

八节点六面体等参实体单元，包含总刚集成，可用于弹性计算(eight-node brick element with trilinear isoparametric formulation can be used for simple analysis)

matlab编写的基本图像处理程序，对图像处理初学者有很大帮助。(matlab prepared the basic image processing program for image processing are very helpful for beginners.)

用于对周期性的数据趋势进行评估与分析，特别适用于具有某个周期的数据组。(For periodic assessment of the data and trend analysis, especially for data having a certain set period.)

Fast ICA，一种ICA的快速算法，有完整的论文（两种格式，pdf和ps的）(Fast ICA, the ICA a fast algorithm, a complete paper (both formats, pdf and ps))
