精度颇高的转子临界转速及不平和响应算法，主要采用了传递矩阵法(High precision of the rotor critical speed and the uneven and response algorithms, mainly in the transfer matrix method)

说明：  关于遗传算法的matlab程序，可实现gatool中的大部分功能。(Matlab genetic algorithm on these procedures is to realize most of the functionality gatool.)

复调制的FFT变换，即ZOOMFFT，以及ZOOMFFT和FFT本质的注释，调试过，肯定没问题，希望对大家有帮助(FFT transform complex modulation that ZOOMFFT, as well as the nature of the comments ZOOMFFT and FFT, debug, certainly no problem, we want to help)

说明：  删除卷积码的matlab仿真,广泛应用于通信系统中(delete the Matlab simulation, widely used in communication systems)

某炮弹质量为20KG，直径120mm，出炮口是的初速为800m/s，初始发射角等于45°，试计算弹道。解答过程与程序详解(A shell quality is 20 kg, 120 mm in diameter, out of the muzzle velocity of 800 m/s, initial emission Angle is 45 °, try ballistic calculation. The solution process and procedure, rounding)

用于眼球阴影区域提取的matlab程序，附带测试用图像(Eye shadow zone for extraction matlab program, with test images)

用matlab实现的曼彻斯特 DLFQKC编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的WMMygYW 的通信原理课件上的形状一模一样。 .(With Manchester DLFQKC encoding matlab realize. 50 duty cycle (adjustable) . Draw time-domain waveform and frequency domain power spectral density. Results with BUPTWMMygYW Exactly the same shape Wenbin communication on the principles of courseware.)
