GDDEMO runs a little demonstration of gradient descent in Matlab. Launch Matlab, and type gddemo to get started.

自己收集的matlab遗传算法的资料，耐心看完会有收获(Own collection of matlab genetic algorithm data, there will be harvesting the patience to read )

程序采用的是两层循环上实现位移谱的求取。内循环实现在地震波下由上一步所得到的位移、速度和加速度得到下一时间间隔后的位移速度和加速度；外循环实现在不同结构自振周期（频率）下遭遇地震波的响应。(Program uses a two-layer loop on calculate displacement spectra. Cycle based on seismic waves obtained the previous step under the displacement, velocity and acceleration are next after the interval velocity and Acceleration outer loop implementation in different natural period of structure (frequency) the response under earthquake wave.)

说明：  此程序是一个将灰度图象转化为二值图象的程序,手动选择阈值(This program is a the gray image into binary image of the program, manually select the threshold value)

本书讲述了matlab仿真技术与应用教程,钟麟王峰主编(This book tells the Matlab simulation technology and application tutorial)

一些介绍系统参数辨识方法的论文，包括迭代梯度算法，最小二乘算法等。很好的资料。(Some paper describes the system parameter identification methods, including iterative gradient algorithm, least squares algorithm. Good information.)

可以在matlab上点击，获得点击的坐标值(failed to translate)

说明：  the code is dealing with the detection of faces in an image. it is basically a face detection code

详细介绍了轨道方程，轨道六要素，以及坐标计算方法，包括椭圆轨道面坐标、大地空间直角坐标以及经纬度坐标的计算方法(The orbit equation, the six elements of orbit and the coordinate calculation method are introduced in detail, including the calculation method of elliptical orbit, plane coordinates, geodetic space, rectangular coordinates and longitude and latitude coordinates)
