matlab仿真作业，使用simulink，包括lorenz方程、卫星轨道、调制与解调(matlab simulation operations, the use simulink, including lorenz equation, satellite orbit, modulation and demodulation)

滑动聚束模式的RD成像。聚束模式SAR中,天线始终指向场景中心,合成孔径的长度比相同条件下的条带式SAR长。对于滑动聚束模式SAR系统,由于天线的指向变化与两者都不同,所以与条带模式相比,其合成孔径更长,而且测绘带区域比聚束模式更大 (The Sliding Spotlight model described in the article can geta better resolution than strip-map mode and better observed area than spotlight mode.by steering the antenna on a point further away the radar than the area beingilluminated which can be regarded as coming the underground. By doing this, thismode can get good combination between the resolution and observed area. )

matlab source code and assignments

运用matlab的SimMechanics模块进行平面曲柄摇杆机构的仿真(The simulation using the SimMechanics module of MATLAB planar crank rocker mechanism)

CEEMD算法文件，已经过测试，可完全能够使用！！！(CEEMD algorithm file)

生成矩阵和校验矩阵的生成在MATLAB语言下的实现(Generated matrix and calibration matrix generated in the MATLAB language to achieve under)

说明：  matlab最优控制的作业 请各位高手多多指教(Matlab optimal control operations please master exhibitions)

该程序用matlab编写数值积分方法，包括梯形公式，Simpson公式和Romberg算法，在main.m文件测试三类算法。这是数值计算方法是必须掌握的代码。(The program is prepared using matlab numerical integration methods, including trapezoidal formula, Simpson and Romberg algorithm for three kinds of formulas in main.m file for testing. Is the numerical calculation method must master code.)
