Navier-Stokes

Matlab编程实现FFT变换及频谱分析的程序代码（适合初学者加强理解）。（1)用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图；(2)进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选；(3)做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱；(4)用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图。(Matlab codes for FFT Understanding which contains sine wave,rectangular wave and the reletaed frequency spectrum figure about MSE,Log,IFFT and so on.)

这里是matlab与数值分析的学习资料，对于初学者非常有用。(Here is the matlab and numerical analysis of learning materials, is very useful for beginners. )

这是一个有关于遗传算法用于参数优化源码的例子(It is a genetic algorithm is used to optimize the parameters of the source code examples)

通信系统的简单蒙特卡洛仿真,利用系统中断概率(teleconmunication sample sistem simulation BER to SIR curve )

性能最好的单用户能量检测频谱感知，都是最好的东西，曲线和理论值进行比较，效果明显。欢迎批评指正。(The best performance of a single-user energy detection spectrum sensing, are the best thing, curves and theoretical values ​ ​ are compared, the effect is obvious. Welcome criticism.)

关于pll的simulink模型，希望对大家有用。(a module of pll by using simulink.hope it be helpful)

说明：  此代码通过模拟退火算法优化BP神经网络进行汇率预测(This code optimizes BP neural network to predict exchange rate by simulated annealing algorithm)

说明：  用于地震信号的剖面生成，有助于观察采集到的信号(For seismic signal profile generation, it is helpful to observe the collected signals)
