matlab实现的小球运动的源程序，不错的matlab GUI 例程(Matlab achieve a small ball of the source, a good GUI Matlab routines)

it shows the Antenna Directivity Pattern by using matlab

其中包含了一些不同条件下的粒子群算法，希望对大家有所帮助。(Which contains a number of particle swarm algorithm under different conditions, we want to help.)

关于聚类算法 层次聚类的一些说明和简单的例程实现(About clustering algorithm- some explanations and simple routines to achieve hierarchical clustering)

说明：  打开视频文件,将图片分割成若干帧，并将每一帧存起来(open the video)

内点法matlab程序，其中包含对经济性要求条件(Interior point method matlab program, which contains the conditions of the economic requirements)

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.)

hopfield神经网络的基本程序，给出了网络连接以及输入输出之间关系的基本网络(The basic program hopfield neural networks, giving the network connection and the basic network between the input and output)

MATLAB坐标轴设置，包括颜色的设置，步长的设置，添加图例，改变背景等(MATLAB axis is provided, including color settings, step size settings, add legend, change the background etc. )

用MATLAB实现了基于pca的特征提取方法，有效地完成了识别，是识别的经典例子(PCA to achieve recognition )
