PSD of a sinusoidal signal

利用模式理论，对给定几何尺寸以及折射率分布的光纤进行模式求解与绘图，该程序给出LP11模的求解与绘图。(the LP11 mode of the fiber)

说明：  混合群智能优化的模糊PID控制,该设计用于汽轮机调速器的设计(A Hybrid PSO_Fuzzy_PID Controller for Gas Turbine Speed Control)

基于matlba的常见信号设计，全部都经过实验验证，可作为子函数使用(Common Signal Design matlba based, all through experimental verification, use as Functions)

微波与天线，课程中基于MATLAB的虚拟实验。对上课很有帮助(Microwave and antenna, the virtual experiment based on MATLAB course. Very helpful for class)

数值分析里面的高斯消元法利用全主元消去的程序(Numerical analysis method which use the Gaussian elimination procedure all main element elimination)

灰色系统知道系统的一些简单信息，但是并没有完全了解该系统，只能根据统计推断或某种逻辑思维来研究该系统。(The gray system know some simple information system, but did not fully understand the system, to study the system can only be based on statistical inference, or some kind of logical thinking.)

最近用Mega128写了一个128点FFT程序，浮点运算，加汉宁窗。由于窗函数和旋转因子通过查表得到，所以速度还可以，程序中给的初值是通过高速AD采集的20KHz正弦信号。计算结果与Matlab的FFT函数得到的结果相同。 (Mega128 recently wrote a 128-point FFT procedures, floating-point operations, Hanning window. Since the window function and the twiddle factor look-up table has been adopted, so the speed can also be, the initial value to the process through high-speed AD collected 20KHz sinusoidal signal. The calculation results with the Matlab)

雷达发射信号为线性调频信号的雷达计算仿真，可以直接运行的matlab程序。(Radar Chirp signal for the radar signal simulation can be run directly matlab program.)

matlab/simulink 三种方法：追踪法、比例导引法、平行接近法的弹道仿真(matlab/simulink tracing method, proportional navigation law, parallel close to the law)
