image processing for academic

理论力学——霍曼轨道运动的matlab计算机模拟 主程序名 hmgd.m 函数名 界面程序名hmgdfun.mhmgdgui(Theoretical Mechanics- Hö rmann computer simulation of orbital motion, matlab main program interface function names were hmgd.m program name hmgdfun.mhmgdgui)

说明：  通过在MATLAB平台上比较BP神经网络的三种训练方法－trainbr traingdm trainlm.并且网络中加入噪音！(through MATLAB platform comparison BP neural network training method for the three-trainbr traingdm trainlm. Network and add noise!)

this code is used for frequency modulation in matlab

解析法建立挤压油膜阻尼器稳态数学模型并仿真特性关系(Analytical method SFD to establish steady-state characteristics of the mathematical model and simulation relations)

说明：  主要用于制作编译码的具体的中间环节完成一些通信平台的搭建(Mainly for the production of concrete in the middle part of decoding the completion of some communications platform structures)

实现一个ARMA模型的功率谱估计，实例中承载的是窄带信号，也可以改成宽带信号的(ARMA model to achieve a power spectrum estimation, the instance is hosted in narrow-band signals into a broadband signal can also be)

雷达成像RD/CS/RMA三个算法matlab实现(The radar imaging RD/CS/RMA three algorithms matlab to achieve)

一本介绍了如何使用Matlab的工具书，新手特别容易上手(a file demonstrates how to use Matlab,new learner can handle matlab quckily.)

This function implements a Voice Activity Detector algorithm based on signal energy, zero crosses, frequency, and adaptative thresholds.
