使用matlab来实现直接序列扩频的调制和解调(Using matlab to achieve direct sequence spread spectrum modulation and demodulation)

本程序实现轨迹生成。基于的原理是飞行器位置和姿态解耦，对其进行独立设计，通过反解出惯性器件信息，从而用于导航。(The program trajectory generation. Based on the principle of the aircraft position and attitude decoupling its independent design, the inverse solution inertial devices used for navigation.)

The Wind Farm (DFIG detailed model demo of the Distributed Resources application library does not simulathe demo that is missing. This file is normally d at the simulation start in order to define an initial state vector that starts the model in steady state.

Single phase A.C. voltage controller using matlab simulink

实现定时控制，非常实用，可以直接调用，有需要的可以下载(Achieve timing control, very practical, you can directly call the need to be downloaded)

Gray world method for color balance

cohere(x,y,M) computes the coherence function using successive DFTs of length with a Hanning window and 50 overlap. (The window and overlap can be controlled via additional optional arguments.) We see a coherence peak at frequency cycles/sample, as expected, but there are also two rather large coherence samples on either side of the main peak. These are expected as well, since the true cross-spectrum for this case is a critically sampled Hanning window transform. (A window transform is critically sampled whenever the window length equals the DFT length.)
