cvx的使用它是一个很有用的MATLAB设计工具 STWC的学习内容(cvx study the use of STWC)

使用matlab编程，首先编写M位的伪随机序列，然后调用产生dpsk信号 (Matlab programming produced by DPSK signal)

802.16的信道建模和仿真，在Matlab上的原代码(802.16 channel modeling and simulation in Matlab on the original code)

the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry. Sliders on the figures allow real-time interactive control of the incidence angle, grating ruling density (lines/mm), wavelength, and diffraction order.(the geometry of a diffraction grating, a commonillustration in textbooks of optics, spectroscopy, and analytical chemistry.Sliders on the figures allow real-time interactive control of the incidence angle, grating ruling density (lines/mm), wavelength, and diffraction order.)

说明：  MATLAB课件 给那些电子信息工程的学生看看 很好的软件 (MATLAB Electronic and Information Engineering courseware to students who look very good software)

说明：  matlab代码实现目标检测功能，进行二维单元恒虚警检测。(Matlab code to achieve target detection function)

实现对信号的连续、离散小波分解，程序简单易读(Achieve continuous signal, discrete wavelet decomposition, the program simply read)

Fixed-point for functions of several variables (Function fixed_point_systems(x0, N) approximates the solution of a system of nonlinear equations F(x) = (f1(x), f2(x), ..., fn(x)) = 0 rewritten in the fixed-point form x = G(x) = (g1(x), g2(x), ..., gn(x)). This is done by the user at the bottom of the file. The sub-function G(x) has to be updated accordingly with the given system. The iteration scheme x(k+1) = G(x(k)) is implemented until condition |x(k)- x(k-1)| < tol is met, starting with an initial approxiamtion vector x0. If, after N iterations, the stopping criterion is not reached, a message concerning the iterated x s is displayed. the output consists of iterates of each variables x1, x2, ..., xn in each column. )

说明：  本资料系统讲解了随机信号的基础知识，对于以后信号处理的研究有一定的借鉴性。(The information system to explain the basics of random signals, signal processing for future research have certain reference.)

tracker.m Continuously keeps taking snap in real time and sending to function isub for tracking isub.m It is a function which takes two consequent frames, subtracts them(background gets subtracted), converts the resulting image into binary, finds the centroid of largest area of connected pixels and marks it(tracks it) The code has been tested in MATLAB 7.6
