电力系统暂态分析程序源代码，次源代码给出了攻角变化曲线(Power system transient analysis program source code, source code is given second angle of attack curve)

本课件主要讲述MMatlab Simulink中S函数(Function)的写法,其中包含非常实用的S-函数介绍（为什么要引入S-Function？)、S-函数的分类、使用（实例演习）等(The courseware in the main about MMatlab Simulink S function (Function) is written, which contains the S-function is very useful Introduction (why the introduction of S-Function?), S-function category, the use of (example exercises), etc.)

说明：  利用RBF神经网络实现混沌预测，并结合matlab进行仿真，较好实现其功能(Realize the use of RBF neural network prediction of chaos, combined with matlab simulation, better realize its function)

It is a SM johnson filter that is using filter designing concept

混沌函数，很好用的哈，大家试一试哈，真的呀(failed to translate)

合成地震记录是用声波测井或垂直地震剖面资料经过人工合成转换成的地震记录（地震道） 合成记录的制作是一个简化的一维正演的过程，合成记录F(t)是地震子波S(t)与反射系数R(t)褶积的结果。(Synthetic seismogram is sonic or vertical seismic profile data after conversion into synthetic seismograms (seismic trace) the production of synthetic seismogram is a simplified one-dimensional forward modeling process, synthetic seismogram F (t) is the seismic wavelet S (t) and the reflection coefficient R (t) the convolution results.)

Copyed from a Phd paper：This program calculates the reflectivity of a DBR stack。

Generates a pulse with length Tp ,which is composed of Nc cycles of a sinusoidal waveform sinpulse is the waveform representing the pulse

这个 matlab 代码仿真了M-QAM的传输。M的取值不同，调制方式分别为4QAM，16QAM，64QAM等。传输信道为AWGN信道，能出误码率曲线(Digital Unit Impulse Discrete Harmonic Signals and their Linear Combination Harmonic Signal with Exponential Envelope. Periodic Sequence of Rectangular Impulses Mixture of Harmonic Signal and White Gaussian)

拓扑优化设计的经典99matlab代码，对拓扑优化设计感性的可以(Topology optimization design classic 99matlab code, on the topology optimization can be sentimental)
