关于pll的simulink模型，希望对大家有用。(a module of pll by using simulink.hope it be helpful)

The code accompanying Understanding and Implementing the Finite Element Method by Mark S. Gockenbach (SIAM, 2006)(is contained in four directories: 1. version1: linear Lagrange triangles 2. version2: Lagrange triangles of arbitrary degree 3. version3: isoparametric elements of arbitrary degree 4. adaptive: local refinement, a posteriori error estimates, etc.)

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).)

基于matlab的非线性方程组求解的方法(Matlab-based non-linear equation solving methods)

研究正、负线性调频信号的特性，给出其时域、频域图像，以及频率随时间变化曲线。对于初学雷达信号处理者学习LFM信号有帮助。(Study the positive and negative chirp signal characteristics, given the time domain, frequency domain images, as well as the frequency versus time. It s helpful for beginners who study Radar signal processing.)
