基于传输矩阵法的线性啁啾光纤光栅反射谱的仿真研究( linearly chirped fiber grating reflection spectrum of the simulation based on Transfer matrix method )

图象分割算法，这是 active contours分割中外力的选择，通常算法为基于梯度，但对于梯度不清楚的图像，可以采用此方法(image segmentation algorithm, which is active segmentation external contours of choice, usually based on the gradient algorithm, but the gradient was not clear images, we can use this method)

说明：  本程序能够实现棒的横震动，而且在震动过程中能够计算出共振频率(This procedure can achieve the cross-bar vibration, but also in the process of vibration resonance frequency can be calculated)

说明：  matlab有优化处理问题，是模式识别等机器学习的关键(There matlab optimization problems is the key to pattern recognition and other machine learning)

此程序实现简单，便于阅读，易于理解，挺适合初学者学习的。(This procedure is simple and easy to read, easy to understand, very suitable for beginners to learn.)

基于宽带无线通信系统的仿真链路设计，是cdma的多用户检测技术，完整的毕业设计(Broadband wireless communication system based on the simulation link design is multi-user detection technology cdma)

Bit plane slicing using MATLAB

捷联惯导系统放置在室内测试台上做静态测试，测试时间4500s。 1）取前180数据做粗对准（解析对准法）； 2）取第181s~900s数据做精对准（Kalman滤波法）； 3）从第901s开始做纯惯导解算； 4）用国军标的导航系统位置精度评价方法评估系统定位精度（分别计算CEP50 和 CEP95 下的定位精度）。(The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s. 1) take the first 180 data for rough alignment (analytical alignment method); 2) accurate alignment of 181s-900s data (Kalman filtering method); 3) pure inertial navigation solution is performed from 901s; 4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).)

用于分析行走中的人体目标的微动回波分析，改程序为微动分析中的相位调整m函数，可以被移植到其他相应代码中。(Fretting echo for the analysis of human walking target analysis, change procedures for the analysis of micro-m phase adjustment function, it can be ported to other appropriate code.)

说明：  pca、svd、mds 数据降维，用来对数据进行预处理 新人学习，叨扰(pca data dimension reduction)
