matlab教程，详细介绍matlab的入门到精通的过程(matlab tutorials matlab detail the process of entry to the master)

以MATcom为内核的C++程序，调用MATLAB拟合衰减振荡曲线（多线程）(In MATcom as the core C++ program, call the MATLAB fitting damped oscillation curve (multi-threading))

matlab 语言详细实现了GPS捕获、跟踪、解码星历表、定位解算的详细代码，并附有一个程序调用关系的pdf，便于理解结构关系，结合《GPS原理与接收机设计》《GPS原理与应用》更好。 (tlab language detailed GPS acquisition, tracking, decoding ephemeris positioning solver code, together with a program calling relations pdf facilitate the understanding of the structural relationship, combined with the Principles of "GPS receiver design" "GPS principleand application "better.)

基于信息熵和PCA的故障诊断方法，针对状态方程描述(The fault diagnosis method based on information entropy and PCA is described)

对给定集合A和B，能够编出求A和B的并集C的程序。-For a given set A and B, can be compiled out of order to A and B, and the set of C procedures.

基于MATLAB的MFSK调制解调，其中解调包括相干和非相干解调(MATLAB-based MFSK modulation and demodulation, which includes coherent and non-coherent demodulation demodulation)

两种数据读取的方法，希望能给matlab的初学者一定的借鉴，能学点就学点吧学弟学妹们加油啊(Two kinds of data read method, the hope can give matlab beginners reference, can learn some schooling point it drove to the lower classwoman refueling ah)

如上图所示，定向耦合器由完全相同的直波导与弯曲波导构成，波 导芯为宽高比相同（均为 a） 的正方形， 其工作波长，波导材料 对 TE 模式的折射率，及圆弧形弯曲波导的半径 r 等参数如图所 示，若波长为 1550 nm， 归一化光功率为 1 的光波从直波导输 入，请选择适当的满足单模工作的波导宽度 a， 然后给出从圆形弯 曲波导输出的归一化光功率 P4与两波导边缘的间距 d(Directional coupler by the same straight and curved waveguides constituting the waveguide, waves Conducting core is the same aspect ratio (are a) square, its operating wavelength, the waveguide material The refractive index of the TE mode and the arc-shaped curved waveguide of radius r and other parameters as shown Shown, if the wavelength of 1550 nm, normalized optical power a light straight waveguide input In, the appropriate work to meet the single-mode waveguide width a, and then is given a circular bend Curved waveguide output normalized optical power P4 and two edges of the waveguide spacing d)

This package implements basic Principal Component Analysis and Eigen Faces in Matlab and tests is with grayscale portion of the FERET database. Images are not preprocessed and it is up to the user to preprocess the images as wanted, not changing the filenames.

空间平滑算法的作用是估计源数目，特别的是可以估计相干源个数(space smoothing technology,and estimate the number of correlation sources.)
