利用fortran语言编写的通过beamwarming差分格式求解一维激波管黎曼问题。(Fortran language through beamwarming difference scheme for solving one-dimensional shock tube Riemann problem.)

清华大学章毓晋老师图像分析最后一次作业答案(The answer for the last homework of image analysis by Yujin Zhang, Tsinghua univ.)

直流斩波电路的mtalab仿真实例，可以观察波形，便于延伸各种仿真，继续仿真(DC chopper circuit mtalab simulation example, the waveform can be observed, to facilitate extension of the simulation, the simulation continues)

说明：  单变量寻优基本算法的原码，包括区间取半法，0。618法、FIB法，牛顿法、二次逼近法、三次逼近法。(single- variable optimization algorithm of the original code, including the semi-admission interval, 0. 618, FIB, Newton, quadratic approximation, three approximation.)

说明：  假设每个延时单元延时10ms.被传输的基带信号x(t)是一个0，1交替变换的矩形二进制脉冲序列，脉宽为10ms，并假设x(t)通过一个稳定的散射信道后才到达均衡器，成为2径信号，这两路信号幅度相等 ，相隔15ms。用MATLAB实现一个2级LMS均衡器(equalizer)
