"introduction to the finite element method in electromagnetics" 配套源码。 内容包括了1-D，2-D的4~5个FEM例子，适合初学者用。( Introduction to the finite element method in electromagnetics auxiliary source. Includes a 1-D ,2-D FEM of 4 to 5 examples, for beginners to use.)

特征空间方法是现代谱估计的重要方法之一。针对噪声中的复正弦信号的模型，通过特征矢量的方法进行信号空间的分解。通过将信号空间分解为谐波信号空间和噪声信号空间这两个相互正交的空间的方法进行谱估计。Pisarenko,Music,ESPRIT算法都是这一类方法的重要算法。我们通过对不同算法进行比较分析不同算法在各种状况下的表现性能。并针对ESPRIT算法的各种改性和提升进行对比和测试。(Feature space is one of the modern spectral estimation method. Complex sinusoidal signal for the noise model, by the method of the feature vector for the decomposition of the signal space. By decomposition of the signal space to the space harmonic signal and the noise signal space, the method of the two mutually orthogonal spatial spectrum estimation. Pisarenko, MUSIC, ESPRIT algorithm is an important algorithm of this type of method. Different algorithms, our comparative analysis of the performance of different algorithms performance under a variety of conditions. And for a variety of modification and upgrading of the ESPRIT algorithm to compare and test.)

计算任意两点（给定经纬度）的球面距离，并画出轨迹图。(Calculating any two points (given the latitude and longitude) of the spherical distance, and draw trajectories.)

计算亚波长光栅衍射效率,PBS,即偏振光分离(calculate subwave grating diffraction efficiency)

说明：  本源程序为采用IV辅助变量算法法进行供电负荷预测的，后面还自带了进行模型检验的部分，很适合电力专业的学生学习使用(The source code for the algorithm using method IV auxiliary variable power load forecasting, the model behind the test also comes with some very suitable to use the power of professional learning)

matlab开发的地震数据的波形图绘制程序，能够直接使用，操作方便(matlab drawing development process of seismic waveforms)

说明：  关于MATALAB的书籍文章很经典值得一看解压后必须使用超星浏览器观看(MATALAB article on classic books worth a visit after decompression must use a browser Chaoxing Views)

说明：  迭代学习控制源代码，希望学习次控制方法的朋友能和我交换资源(Iterative learning control source code, want to learn controls the method of exchange of resources and my friends can)

预测控制鼻祖文章,纯英文的,写的不错,大家可以(Predictive control article originator, pure English, written well, everyone can)

用MATLAB在产生的观测数据中捕获其中PRN 号码为“5”C/A 码。 （1） 观测数据应该有一定的多普勒频偏D f（-10kHz〈D f〈+10kHz）； （2） 加入高斯白噪声，使其信噪比为-20dB； （3） 捕获成功后，应给出捕获标志，并给出估计的频偏和码偏值。(Generated by MATLAB in which observed data capture PRN number is " 5" C/A code. (1) there should be some observations of Doppler shift D f (-10kHz < D f < +10 kHz) (2) by adding Gaussian white noise, so SNR is-20dB (3) capture success After the capture flag to be given, and given the estimated frequency offset and code bias values.)
