利用拉普拉斯变换的思想，通过对数据进行差分，近似得到拉普拉斯变换后的结果，然后检查正负交换的位置，则此为极值点位置，利用此思想得到极值点的位置。(Using the ideas of Laplace transform of the data by the difference approximation get results Laplace transform, and then check the position of the positive and negative exchange, this is the extreme position, take advantage of this thinking of getting extreme points location.)

Processing Image using GUI matlab ...........................................

matlab中编写的船舶动力定位PID控制函数，适于DP建模动态模拟分析(written in matlab，Ship Dynamic Positioning PID control function, suitable for DP dynamic simulation modeling )

采用有监督学习的hebb规则实现权值学习的学习，给出实际例子，单神经元自适应控制器.(Weight is realized by using supervised learning hebb rule of learning, gives a practical example, the single neuron adaptive controller.)

本程序是一个关于基于二相制调制的扩频仿真程序，希望和大家交流一下。(This program is a spread spectrum modulation on bpsk-based simulation program, and we hope things about.)

You can learn BPSK modulation in OFDM Systems BPSK means binary phase shift keying modulation. Basically OFDM uses fft/ifft modulation. and add cyclic shift and remove to cancel inter-symbol-interference.

详细介绍了双馈感应发电机系统，包括转子侧和网侧控制系统(The doubly fed induction generator system is introduced in detail.)

对CSAR成像的波数域算法的论文及代码，能做到插值以前，较为有用(For CSAR wavenumber domain imaging algorithm paper and codes, we can do before interpolation, the more helpful)

说明：  微电网虚拟同步发电机控制的MATLAB例子，simulink可以运行(Matlab example of micro grid virtual synchronous generator control, Simulink can operate.)

利用小波进行图形的降澡,对于一般的图像来说效果明显(Carries on the graph using the wavelet to fall the bath, is obvious regarding the general image effect )
