飞行控制仿真，在某一状态点下，选择横侧向和纵向回路中的一个进行控制。分析系统的响应、极点位置与稳定性，能控能观等特性。(Flight control simulation, in a state, select a control in the horizontal lateral and vertical loop. Analysis system response, the pole position and stability, controllability and observability, and other features.)

天线圣经，每个学习天线的人必看经典。其中对天线的原理性描述非常深刻。(Antenna Bible study each antenna, a person must classic. The principle on which the description of the antenna is very profound.)

刘金坤《先进 PID 控制及其 MATLAB 仿真》书上第一章源程序。供大家参考。(Liu Jinkun " Advanced PID Control and MATLAB simulation," the book' s first chapter source,)

模态参数频域识别，是指在频率域内识别试验结构模态参数的方法。(The frequency domain modal parameter identification, is the recognition test in the frequency domain method of structural modal parameters.)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)
